Spoiler Alert!I give it a 9/10. Only losing a point because of the lack of information given to the audience. Considering the amount of hype they put out about the monster and how much of a big deal it was, they could have showed us more of it, or told us more about it. I totally understand that the footage would be limited because it was supposed to be shown from a specific point of view, but the LEAST they could have done was at the end during the credits maybe have a newscast from another part of the country talking about the military taking action off in New York against a creature and then discussing what they know so far about it and the events that transpired.
But all in all, great flick. Blair Witch for the 2000's. Well crafted for what it's supposed to be.
