Saw this last night and i really enjoyed it. Alll the talk of gore and violence had made me a little worried, as I usually don't enjoy that kind of thing, but in the end, I really really like it.
The only part I found truly disturbing was the cut off hand... the rest of it was so "comic book" it didn't bother me at all.
I really enjoyed how the stories tied together and thought the use of color was very well done (except when Willis's character was all in color, don't think that worked in its place).
Kevin was a perfectly disturbing character, and opposite of Marv was great. I particularly enjoyed the fact that the "pretty boy" was the totally evil guy, and the mangled "freak" was the good guy. That's good stuff.
I didn't get the same "could cut 10 minutes" feeling everyone else had, but then, I left at the beginning of story 2 for abotu 5 minutes, and when I came back they were still in that apartment... so maybe that's where things got too long for people
.
All in all, very enjoyable, but not a repeat view I imagine. It did make me want to read the books, though...
