I probably would have liked the film better, if i hadn't had higher expectations based on the reviews. But I found it to be just a pretty standard, mostly well acted, origin story.
The big gimmick here - the found footage look - works great in some parts (especially during the final battle, there are a few moments when you really feel like what it must be like to be a civilian during a superhero battle), but in others it was completely unbelievable. I think it would have been better if they had gone the District 9
route and clearly switched between "found footage" and being a normal film.
