While it's not for everyone, Miami Vice is definitely a movie for me. I'm a big fan of heist type movies with internecine dealings, people carrying guns around, etc. The tone of this film was really nothing like the TV show. It was very gritty and serious, with punishing and gruesome gunfights, rough camera work and grainy postprocessing effects to emphasize the feel.
The story did take a while to get moving, and the plot was, at times, a bit hard to track, which detracted from the overall experience. On the other hand the cinematography worked for me, created suspense with the camera's position and movement, and the grainy night scenes gave an impression of heat, sweat and tension.
The final gunfight was very impressive, with great sound, relative realism, and brutal consequences for the participants. The blend between Hollywood and real life was perfect for my taste. Nothing goofy, like leaping dual pistol shooting, but a few improbable shots here and there to add some flash to it.
I just liked the movie a lot. I can point to so many flaws in pacing, in the plot, in the English skills of Li Gong... But it all just doesn't matter relative to the overall effect.
