If you love the Graphic Novel, You'll Be Disappointed As a stand alone movie, this is a fun ride. It is beautiful, chock full of Easter Eggs, actual historical references, and has a good pace.
Unfortunately, they chose to make some rather bizarre changes to the original story that I just can't quite stomach.
If they hadn't messed with such pertinent aspects of the story, this would have gotten close to a ten. It is metal, truly R and that makes it very awesome.
But, if you are a fan of the original source materials, be prepared to walk away a bit disappointed.
