I really enjoyed the movie. Effects, cinematography and all.
About the fire, anything that doesn't work in real life, that we know doesn't work in real life or in Earth physics is hard to sell in VFX. The fire in the forest looked good, because we've all seen wood burn and footage of forest fires. People don't burn like a propane stove, especially while moving and gently lifting your arms, etc. It's hard for the brain to accept. Even then, I didn't' feel bad about it. I was so drawn in that I really didn't notice or care. It was supposed to be fake anyway.
As far as the tight shots, I didn't notice in a bad way. I thought it fit the subject matter well. The violence was more personal and wrenching like it was intended. The author is pretty vocal against violence as a form of entertainment, so considering that and considering it was kids killing kids, I thought it was handled great.
Finally, some really subtle stuf I did like considering cinematography (and sound design) were how well the camera style changed to fit the emotion. For example, backstage before her first interview the camera was steady and smooth. Then, as her time came and she stepped out on stage, the camera work slowly became closer, more shaky as the sound became muddled, the echo of applause drowning everything else out. It really made you as nervous as she was at the time. Same with some of the fight scenes, when you had a chance to breath it was easy, then when all hell broke loose it kept the tension right.
I wasn't a fan going in. In fact, I was a little nervous from all the comparions to twilight and how excited every teenage girl in America was to see it. I'm sold now though. Great story, I don't think I breathed the last hour or so.
