The movie offers a wide variety to offer the audience. It has humor, action, and even Nazis as the bad guys!1 Some of the special effects could have been directed a bit better. When I saw the trailer for this movie with a group of friends our response was "Matrix did it!" But if one looks past the fact that other action movies like The Matrix or Chow Yun-Fat's own Crouching Tiger, Hidden Dragon have better special effects, then the film can still be enjoyable. It's a light action movie that's generally unoffensive.
If you're in the mood for a light action movie that has some good effects and chuckle-able humor, then I'd suggest checking out Bulletproof Monk.
1. Man! I hate Nazis!
