Personaly i really enjoyed this film, although i do know a few people who dont feel the same.
The films opening really gives you a feel on how the rest is going to be, with each actor getting a suitable scene that best suits their acting styles.
Rober Deniro opens it with the "lowdown" on cop life, he gives the most serious, realistic and harsh version on how the average dectective lives and does their job. "..if you break the law, i will do all in my power to hunt you down and put you behind bars, that is a promise." Then the camera pans out and hes talking to an elementary school class! Which is the first of many humerous moments. He finishes it up by sayin that being a cop is not exciting and is not what you see on TV. The it immediatly skips to eddie murphy giving an excellent over the top performance whilst talkin gto his captain. Things like jumping off roofs shooting 2o guys, then you discover that he was just at an ordition for a television reality show. Where the humour really kicks in is 2 seconds later when you see that he is actually a real cop, which is quite sad!
The two actors hate each other at first, but over time the usual happens and they learn to like and learn from each other, becoming a team.
This film is worthit for the unique idea, the action and humour, and the great cast, including William Shatner from the original startrek who plays himself! If you happen to run into this film then hear it out, you wont b dissapointed.
