For an action comedy, this is by far one of the best I have seen in a while. Even though the movie may come off as a bit under budget or ordinary, the story is worth watching. This movie left me with a great 'after-taste.' Although watching it again may eliminate some of the mystery behind the story, it is still worth a second watch (even if just for all the jokes).
Aside from the story line, I think the cast did a great job in bringing this movie alive (considering it was mostly them that kept me watching despite how ordinary the movie seemed to get.)
Overall: the movie is worth watching at least once just for a good laugh.
