If you're tired of the repetitive, mindless machinations of modern action films, then here's a modern action film you may want to check out. Without a doubt, it's the most "realistic" action film I've seen in a good long while. People get tired after running through the streets or up flights of stairs. Everyday vehicles are not built like the Batmobile - when they take damage, they respond poorly. Oh yeah, most of all this movie gives this important reminder: bullets hurt. People who get shot are virtually incapacitated, and it doesn't take a barrage of 56 of them to take someone down. Even with these real-world limitations - you know, annoying stuff like actual physics and biology that directors and CGI effects dweebs prefer to ignore in favor of pushing their new rendering progs - Richard Donner has constructed quite a white-knuckle thriller. He's old school, the director of the original Superman and Superman II (which are the only ones that count), and here he's as interested in exploring the personal drama as firing shotguns. Bruce Willis gives one of his best performances as a tired cop filled with inner conflict about who to trust - his prisoner (Mos Def), his partner (David Morse), or his conscience. Mos Def does a remarkable job in turning what at first seems like a sniveling worm with an extremely irritating voice into the most sympathetic character in the movie. Seems to offer a climax or two too many, but still an engrossing and hair-raising ride.
