16 Blocks is an incredibly atmospheric movie with some quite incredibly done street scenes. Its intensity draws you in and makes you quickly form strong opinions of each character. I initially considered Mos Def's character to be annoying, but after a number of watches I realised if he hadn't given his character so much character then he would have been inconsequential and that would have weakened the movie severely. I think Bruce Willis was very brave to take the part of Jack Mosley and commit to it in the way he did. He makes this film what it is.
