This is a guy movie of epic proportions. LOTS of CGI-blood. thin story-line, characters falling in-love easily and for almost no reason, lots of killing and ninja's.
An awesome combination. The effects were rad, the acting...okay I guess.
I say watch it out of pure pleasure. It's not going to win any awards and it's loud enough to drown out most teenage banter. Not to mention, when the theater for New Moon is filled with teenage girls, all the boys should be in this theater.
