Just got back from seeing it. I feel like there should've been more chemistry or scenes between Scott and Ramona in the beginning, and there were parts that definitely felt hurried, but other then that I think they did a good job with it. Fight scenes were great, and I feel they were definitely better then the comic.
I do end up missing a lot of the stuff that had to be cut, like Envy's backstory and just seeing them hangout, and it kinda makes me wonder how it would've gone if they did two movies, splitting the story where the third boyfriend is offed. Though given the BO, doing it in one shot might've been for the best.
Here's hoping word-of-mouth helps it, if only a little. My brother, his friends and some of my coworkers ended up seeing it and thinking it was amazing (and I don't think any of them even knew it was a comic originally).
