Just got done watching American Gangster, I would post the link, but I'm not sure where the site comes down on those sorts of things, and I rather not get banned.
Anyways, great movie, fantastic acting(who would of guessed right with two Oscar winning leads), right up any fan of gangster/mob movie fan's alley. Everything was just well put together, the story built slowly, but I never lost interest, the characters Crowe and Washington play both feel very authentic, which is very important obviously because it is based on a true story. There is only one scene that I would say is solely used to build drama within the movie, and is unrealistic, but the film does such a great job at keeping everything realistically that the particular scene does hang in your mind through the whole story. There is an interesting bit of irony between the two leads, based on their character, they replicate the general feeling of just a corrupt sleazy state of affairs within the police force, once again without going overboard and seeming unrealistic. The entire movie does a good job of incorporating the time period, where it acts more than just a background, but a piece of the puzzle. I highly recommend this movie, also for those that enjoy it, and wish to watch a movie based more solely from the perspective of Crowe's character, "Serpico" too is of the same material that Crowe's character deals with and is an even better movie than this, also based on a true story.
9/10 Great Movie
