Saw it last night with a bunch of people and most of the theatre was laughing in unison at much of it. I'm sure some people laughed that nervous laugh, while many (including myself) were doing so out of ridiculousness. I did think there were some isolated good parts, but overall I found the most unbelievable thing not to be the paranormal activity, but instead to be the humans response to all of these events. So unbelievable that it was laughable more than it was scary. I don't recommend it...
