Amazing visuals, a great soundtrack tons of action ... what more could you want? Well, the whole movie seems forced and it really seems like large pieces are missing from the film. I imagine this was to get a PG-13 rating as the film pushes the boundaries and rather than modifying the script it seems as though things were just dropped wholesale.
A few portions of the film have awkward scenes that abruptly end, almost mid sentence. I'm not sure if this was intentional or just a hack-job to get the rating the studio wanted. But it makes the movie seem almost unfinished. The basic story is fun and feels like a comic book (which it never was) although the whole "reads like a video game" thing that other critics complain about doesn't bother me. The disjointed nature of the abrupt cuts is more problematic.
If you can get past the flaws this is a really fun movie. The visuals are amazing and the soundtrack really adds to the action scenes. The story is slightly weak, and I think the film within a film within a film thing is getting old and lame. But if you're just looking for a fun film filled with eye candy this is just what the doctor ordered. If you're looking for any depth well maybe a lobotomy is in order.
