The short form is that I loved, LOVED the look of this movie, the feel of this movie. Some shots look like they are just ripped from Frank Miller's comic, which makes sense as he was a co-director.
The Mickey Rourke section was fantastic, he was great. Surprisingly so, but I don't know much about Rourke. But, overall, I didn't really care about the characters or what was going on. It looked good, and was fun to watch, but I didn't care.
At times the language felt clunky, but that's the neo noir style Miller worked with. It's going to throw a lot of people who might be expecting the Tarantino style slick dialogue.
For a movie I expected to be completely polarizing (some would love, others would hate), I was in the middle.
Grade: a very generous B
