This is one of the few movies I've ever seen where the whole audience broke into spontaneous, loud applause a third of the way in.

It's funny, it's tense, it features two great performances from two actors and the director expertly creates a web of odd tension where you actually don't know what is happening for the majority of the run time.

It's easily one of the freshest, sharpest and most enjoyable films of this year.

The movie is made so realistic it has a lot of that WoW feeling at the right moments and never tooo over the top. the suspense is done so well and the emotion is felt. Very well put together with the music and all.

Noah would have been put in handcuffs and sent in jail for beating up the student and hitting the vice principal in any real school. But then the movie would have ended there. A teacher does not confront an out of control student like Noah without calling the police. No violent student like Noah would be allowed to stay in school. Lame plot.

Okay so this movie was really something.You know that kind of scares you off stalkers and people like that.What Claire did in the end was awful,terrible and macabre maybe.This was something I couldn't even think of doing even to my captor-to be quiet honest!He was a clearly obsessed and this obsession or passion led to his own destruction.I mean he was so blinded by obsession that he couldn't think straight.Well I enjoyed the movie on the whole but the last scene was kind of dreadful for me.And the memory would last.However,Ryan Guzman is devilishly handsome and this character pretty suit him.J-lo is not really my favourite but she did really well though.So on the whole it was prolly based on a different theme which played well I must say!

I'm not usually someone who goes for thriller style films and I may never watch one again after this. Please don't watch this. Choose another decent thriller or watch Fatal Attraction again for a decent version of what this is attempting to be.It started well albeit predictably. And I generally like Jennifer Lopez & Kristen Chenoweth so thought I was in safe hands. But as others say, the lad next door goes from being understandably appealing to a near-divorcée, to a complete and utter maniac in a matter of seconds. He claims he loves her and then does a set of weird things to upset, damage her career, kill her husband and son and so it gets crazier until the final scene which is just plain silly. Her response from the beginning considering he is 19 and therefore over the age of consent is downright ridiculous. Of course, she must be careful being an older woman but all she had to do was pick up the phone and report her worries to the police. I guess that would have been a pretty boring and short film though. Still better than what it became.I'm actually still trying to get the moment where she finally stops him out of my head which is pretty annoying when that part of my memory could be used for something so much better.

I think this movie isn't bad as everybody said. The actor who played Noah "Ryan Guzman" actually is very talented and he actually played the character of a crazy boy with so much Professionalism. I don't know why this film was a bomb but i liked it, i think it is according to your taste. Although, i have a comment on the sex scene, it was so much detailed. Jennifer Lopez in some scenes was overreacting but she wasn't bad either. I hoped that Vicky will live, i don't know why he killed her !! Or in a proper way i don't know why he killed her first!! I can't categorize that movie as thriller because it contains no thrilling scenes but it can be drama!! If it was categorized as thriller then they failed as it is not !! Finally, in general the movie is not bad and i hope you like it
