This show is an absolute classic
Being quite new to start trek, (i'd only really seen the next gen movies and 5 seasons of next gen) someone told me that DS9 was the best of the lot.
I ignored this advice until I watched the TNG crossover show, which was largly set on DS9 and featured Dr Bashir, i thought this looks interesting.
Have 2 weeks off work, i decided to buy the whole lot and watch them all (i know, i'm a loser!)
I must say i was blown away by what i saw, the 1st 2 seasons are prety much standard trek, but a litle bit darker. Season 3, however, when the dominion begin to appear, is where the show begins to shine.
The characters and not clear cut good and evil.
Ben Sisko's got to THE most complex captain in trek history.
Odo, the stern changling head of secuirty, eventually shows his emotional side after many years of lusting after a certain bajoran major.
Quark, the ferengi barkeep (one of treks truely great creations) keeps everyone on their toes, with his dogdy deals, and stolen goods.
and Jadzia Dax, possibly the sexiest woman in sci-fi history.
Lets face it, if your thinking of buying this set, then you've seen most of it, and know what lies in store.
If you haven't, trust me when I say it's worth it, I had never seen it either, and loved it.
I could rant on all day about how good this is.
On a final note, think of it this way
It's not so much a 7 season show, as a 176 hour mini series. The singles still come in seperate collectors boxes,and look great.
