Set in a Chicago County General Hospital, the multi-Emmy winning ER is very much in the tradition established by the earlier Hill Street Blues. Like that series, ER also features a range of strong characters whose personal lives often reflect the turmoil of their working environment. It also similarly features a deft, fast-moving mix of comedy, intrigue and tragedy. It could also be seen as a precursor to The West Wing, in that we regard with some awe the ability of these characters to keep on top of the mounting chaos in their day-to-day lives and the myriad problems thrown at them. In ER, this chaos may mean crack addicts, violent patients tumbling through plate glass screens, vindictive colleagues or a chief of staff who insists that fellow surgeons operate on his sick dog. --David Stubbs

I loved ER's series one and two. Series Three was good too but I missed and was greatly saddened by a main character's departure. Series four was the first series I didn't captured by the magic,however.

Dr Conray (I think her name was) and Benton's relationship was cool, and ER continues to give off wild situations and alot of drama and heart. But it was too soapy, Carter (I hate him like crazy) still being there and being so annoying, I wished Maggie Doyle (Jorja Fox) was given a bigger role, she would have been more interesting that this blonde doctor with the complex name (luckily she's leaving soon - even though I would have been more happier with Carter leaving)

All in all, it's a great series, but you may feel slightly disapointed compared to the standard left from the previous three series. Series four is always a haunting for showes (Scrubs for instance) but hopefully ER will be able to get back on form (by a few episodes of series five - yes it does) Keep watching this show, please! Despite this series.

ER Series 4 Cast: Anthony Edwards (Dr. Mark Greene); George Clooney (Dr. Doug Ross); Noah Wyle (Dr. John Carter); Julianna Margulies (Nurse Carol Hathaway); Gloria Reuben (PA Jeanie Boulet); Laura Innes (Dr. Kerry Weaver); Maria Bello (Dr. Anna Del Amico); Alex Kingston (Dr. Elizabeth Corday); Eriq La Salle (Dr. Peter Benton)

The fourth season of ER (Sep. 25-1997-May 14, 1998) is surely one of the series' most memorable, with some extraordinarily powerful and intriguing storylines, excellent scripts and craft, and expert performances from the actors involved. By the fourth season, ER had established its own distinctive style, and so by this time the work retains an effortless quality, even though each episode is as intricate and complex as before.

Each character undergoes some important changes in this season. Greene (Anthony Edwards) tries to get his life back in order after the violent attack he suffered in the third season, and enjoys a relationship with the loving but 'needy' new desk clerk Cynthia Hooper (Mariska Hagertay, 4.2-4.16.) Greene also visits his parents in San Diego in two episodes, "Fathers and Sons" and "Family Practice," which brought the action outside of the ER and outside Chicago for the first time in the series.

Ross (George Clooney) is a changed man this season, staying loyal and responsible to Hathaway (Julianna Margulies), intent on getting their relationship to work. Professionally, however, it's a different story as he jeopardises his career in the season's final episodes with a controversial "ultra rapid detox" on a seven-month-old addicted to heroin. Hathaway's big arc is the opening of a clinic in the ER, after deciding against going to medical school. But, unusually, it is Hathaway who struggles to commit to Ross this season rather than the other way round.

Carter (Noah Wyle) has left Surgery in favour of an unpaid ER internship, where he is "secondary" to (the underused this season) Doyle (Jorja Fox), with whom he enjoys an interesting rivalry. Carter realises the joys of being a doctor caring about his patients rather than only performing surgical procedures. Two of his big storylines this season are the difficulties with his cousin Chase (Jonathan Scarfe), who is addicted to heroin, his struggle for independence from his family's vast fortune, and his would-be relationship with Del Amico (Maria Bello.)

Del Amico, who arrived towards the end of the third season, has some big storylines in this season. Her relationship with Carter is one of the season's most memorable interactions, as is her sometimes torrid relationship with fellow paediatrician Ross.

Boulet (Gloria Reuben) is another key player in this season. She is fired from County as part of her friend Kerry Weaver's (Laura Innes) plans to make the hospital more cost-effective, but reacts strongly and controversially uses her HIV status to ensure that she wins her job back. Her relationship with Weaver takes a downturn for much of the rest of the season, and she is also hit by the end of her marriage to Al (Michael Beach) when he takes a job in Atlanta. Her most memorable storyline, perhaps, is her emotional relationship to cancer patient Scott Anspaugh (Trevor Morgan), son of Chief of Staff Don Anspaugh (John Aylward.)

Weaver finds her promotion to Acting Chief of the ER, following Morgenstern's (William H. Macy) heart attack, not without its difficulties. Her friendship with Boulet is severely tested, and she grapples with various problems. She also enjoys a romantic entanglement with Ellis West (Clancy Brown), who is a member of Synergix, a group who help with budget cuts - but Weaver goes on to have some serious reservations.

A newcomer also enters into proceedings - English surgeon Corday (Alex Kingston), who has some of the season's biggest storylines and is arguably the most significant character in the season. She brings a verve and humour to the ER, and is forthright as she pursues Benton (Eriq La Salle.) Her stormy relationship with her sponsor, Robert "Rocket" Romano (Paul McCrane) is highly entertaining, and receives some knock-backs when she elects to take the controversial HemoAid study to the ER.

Benton (Eriq La Salle) is noticeably more light-hearted and mellow this season, which can be attributed both to his relationship with Corday and also his new fatherhood. His friction with Carter reaches a small climax before subsiding again, but this season shows an interesting new side to this character.

The extras here are not plentiful, to say the least - a documentary on the unusual live opener "Ambush" (which is perhaps the weakest episode of the season) would have been insightful, but the outtakes are interesting and are often as funny, well-written, and engaging as anything that made the final cut. Indeed, a criticism levelled at this season is that certain plots were not resolved satisfactorily - the serial rapist storyline, the elderly woman infected with HIV, for example. More scenes of these storylines are in the outtakes, deleted from the final cut. But on repeated viewing, Season 4 improves no end and reveals itself to be one of the most fast-paced, gripping, and consistently exciting of the series. We learn much more about the characters this time, and the arrival of some new blood - Del Amico, Romano, Corday - adds a fresh new flavour. One of the best.

As i already own seasons 1-3, and give them all 5 stars, i was expecting alot from season 4 and i was not disapointed!!! ER is the best drama to EVER to be on tv. Fact. the scenes are all amazing. all the characters have depth and nothing is done to simply fill time.

ER puts shows like Holby City and casualty to shame. (there laughable after watching ER)

i cant stress enough to you how good ER is. you should buy ALL of the ER seasons now!!!!!!

Season four of ER has a feel to it similar to season two - that is, a little more "soap", a little less "medical drama". For the first real time we see the bulk of an episode take place outside of the ER, indeed outside of Chicago, in two very character-based episodes, with one centering around Mark Greene and the other around Doug Ross. While both episodes help us to better understand those two characters, I feel it is a bit of a cop-out. For me, the show sparkles more with creativity and intelligence when the characters are revealed through their work place; otherwise the show becomes just yet another soap.

The editing in this season is also not up to the high standards of the previous seasons, with many of the medical sub-plots often under developed and under explained, usually in order to give more screen time to the above-mentioned "character drama". This leads to some episodes feeling highly fragmented, although this feeling did subside somewhat on a second viewing.

The audio and video transfer are excellent - great depth of sound and colour, I have no complaints in that department. Also good to see is the preservation of the widescreen aspect, although the very first episode is in 4:3 - although I imagine that is because of the conditions under which it was filmed (see below).

Where this DVD falls down considerably is its lack of extras. Each double sided disc contains a collection of additional scenes. There is also an easter egg featuring Dr del Amico trading "Yo mamma" jokes with a patient. And that is the sum total of the extras. Missing from this season are the mini documentaries, the blooper reel, and the audio commentaries that were present in previous seasons. The first episode of this season was filmed and transmitted live in the US, and I was definitely expecting a commentary on that episode - I think it would have been fascinating to hear the cast, director, and crew's behind-the-scenes thoughts on this.

My experience with ER is limited to seeing the very occasional episode on television, and the DVDs. From what I have heard, the show has progressively become more and more soap-like, and unfortunately I think I can see the beginning of the slide. Making matters worse is the lack of extra materials on the DVD release that I have come to expect. Still an excellent show, but I can see standards slipping, both in the DVD presentation, and the show itself.

Brilliant season 4! I have been captivated by ER ever since I saw the very first episode in season 1. I was just blown away by the sheer innovativeness of the series. The writing, acting, camera work, story lines, have not diminished since the first opening episodes. The fast action, the clever way the camera work allows you to see the frantic pace when the emergencies arrive in ER and how the various ER staff behave is sheer brillance. I have been known to watch with sub-titles on, much to the amusement of my family, just so that I don't miss any details of the action.

The characters have matured, the story lines are still so good that it's easy to stay involved with everyone of the unfolding lives of the characters. And don't you just ache for things to work out with Doug & Carol! .

Roll-on the sale of series 5!
