Something for the fans of the comics and accessible enough for those who only know the first movie, this far exceeds the traditional paradigms of the super hero movie. There is a compelling human story which serves as a metaphor for existence. This movie transcends the small potatoes love story and tackles uncommon themes such as Order/Chaos, Responsibility/Duty, Love/Regrett, and mostly Sacrifice/Values. Only one word to the wise, this movie is NOT FOR KIDS. I have already seen the movie twice and some of the kids in the theater were scared to death. Seriously, even if you think your kids will be okay... you should screen it first to be safe.
