I thought this was a really enjoyable movie and much better than the first one.
Yep, I'm here with ya. I read the books too and I thought they did a pretty solid job of sticking to the material. Two things - realize not every movie is Citizen Kane, and then go watch Citizen Kane and realize that it's not as good as you remember it to be.
Just like the upcoming Robocop reboot, I'm going to ignore the PG-13 rating (boooo) and just enjoy the flick. (hopefully)
(and then I'm gonna come home and watch the unedited extended Criteron Edition of the original in all of it's absolutely horrifyingly awesome levels of ultraviolence)
