I have to say, I know crank is a completely crazy movie. A lot of what is in the movie can't even exist. But that's the best part... it seriously does not take itself seriously as a movie, but goes for the most mayhem, action, and hilarity possible. That is exactly what I expect and want from this kind of movie.
I would say that this movie was not better or worse than the first, but rather simply... different, but still great.
The one scene that best represents the movie is the last: that of Chev Chelios on fire.
