It wasn't bad. I'm glad the monster turned out to be pretty badass bcause all the fan pictures I saw made it look gay as shit. Oh, did you stay after the credits to hear that radio broadcast go "It's still alive!" and apparently if you pay close attention when that dude and the chick are at Coney Island, the last recording of that when she says "It was a good day" if you pay attention to the background you see some satellite or something slam into the ocean. Apparently it has some connection with the monster. I dunno.
Yeah go see for yourself, the whole blair witch camera thing actually works pretty good for it. i actually jumped at a few parts. the weird thing is that it actually kind of tainted the suspense when they really showed you the monster good near the end.
