If you're just expecting mindless violence, this movie is not for you.
If you just want to be spoon-fed entertainment and not think at all, this movie is not for you.
That being said, I loved it. It placed plot, story and character over the action and special effects. There were only 3 real fight scenes in the entire 2 hours and 12 minutes, which made them even more special in my opinion.
There was no mindless violence. Every single violent act had a purpose, whether it was the advancement of an agenda or an object lesson.
And the many many references were extraordinarily well done, from the Nuremburg rally references to the Benny Hill tribute.
This is a movie you not only need to actually pay attention to in order to appreciate, but makes you WANT to pay attention to it, and that, my friends, makes it my kind of film.
