For saying something negative you have too watch everything. Saying this, it is a totally bad acting teenage movie. They could make a turnover saying that the killer was Amy for some kind of mental disorder and saying that the teacher was a representation of her and the trauma of her father's death which was killed by herself in a act of becoming a serial killer. I would have done that to make it a couple of stars up and to make it quite decent. Even the murder of Amy's mother boyfriend could be explain by her desire of keeping away all the potential men trying to come close to her mother. I hope this is what you wanted as well.

The 3 stars I gave are for Amy's acting skills here. I feel sorry for the directing; her role and acting are the only good things about this movie. Every scene with her is portrayed as it should. However, it fell off the thrill with her co-stars with poor acting skills, especially the villain. This movie requires audio editing to make it better, terrible sound effects and, not on timing, unnecessary and overkilled audio effects were turned off. It gave me a roller coaster feeling and a weird feeling in every way. I thought it is going to be as good as the Gone Girl movie and did not give me any nightmares after.

Honestly, I cannot deal with the main character. I cannot stand main characters that are stupid beyond belief and put themselves and others in danger.

If you're the type of person who can't cope with idiot characters don't watch this movie unless you actually want to be pissed off.

I haven't even watched the whole thing yet I'm literally still watching it as I'm talking and it's driving me absolutely bonkers. I don't blame the characters for not believing this girl she's driving me crazy. The idea was there but I can't get past this main character. Also the music choice is not the vibe for me.
