Keanu Reeves' tirade scene around the middle of the film is the worst "acting" I have ever seen in a mainstream film, period. He is so unspeakably awful, it wouldn't matter if the rest of the movie was Casablanca, it would still be a dud. Unfortunately, the rest of the movie is not Casablanca, but rather a gruesome, unoriginal, futuristic story chock full of cliches, cheap thrills, and gratuitous violence, played for no higher purpose than shock value -- and it doesn't even do that well.
