I watched this movie just now and the only genuinely good thing about it is Bella Thorne as Holly. She actually made an otherwise bad movie scary. Her acting was absolutely amazing and she was genuinely a frightening villain. She felt psychologically interesting with how manipulative and truly insane she could be. She could even make the smallest of things seem scarier than it should be. If the rest of the movie had that kind of talent and dedication that Bella showed with her phenomenal performance, it might have been a good movie. Any scene that she wasn't in was boring, the couple we're supposed to root for have no chemistry (He actually had more chemistry with the psycho chick), the other actors ranged from serviceable to awful, the other characters were boring with no personalities, and is just dull unless it involves Bella Thorne/Holly. So it is still a bad film but Bella saves it from being awful.

I did want to, but I've been hearing some bad things about it. From what I heard, it just sounds like the poor man's version of Fatal Attraction (which is an AMAZING movie that I highly recommend to anyone who hasn't seen it) with teens.
If I ever get Netflix (which I doubt I will), I'll check it out just to see Bella Thorne's performance.
