The 911 Call
*****SPOILER ALERT!!!!!!*****
Anyone else notice that on the "911 call" that opens the movie, Thomas is screaming about how his mother and sister are both dead? Then at the end of the movie, the details state that the mom committed suicide upon hearing of the death of her children (assuming this was after Thomas killed himself in jail after having been accused of raping and murdering Samantha). Not sure anyone has mentioned this already, but if that's not a massive plot hole then I don't know what is.
Apart from that... I thought this movie wasn't bad. It's very obviously a Paranormal Activity "ripoff" (more so than Paranormal Activity was a ripoff of Blair Witch) but it contained some genuinely creepy moments. I'd give it 3 out of 5 stars.
