Deadgirl
Even though I put this movie in horror section, it isn't horror. It's more like drama with horror element. In this movie two guys found a girl who is being strapped to a gurney in an abandoned mental hospital and one discovered she can't die by killing her three times (I'm not sure why he kill her in the first place, he's probably a psychopath long before the movie starts). Anyway the "psychopath" boy decide to keep her as sex slave and rapes her repeatedly while the other one is guilty about what is happening, he didn't know what to do or how to stop him, they're best friends after all. This isn't like any zombie flick (and this zombie chick in the movie can't die anyway, no matter how you kill her). It's watchable and I enjoyed it.
The Signal
I bought this movie after seeing it on Netflix. I really like this movie. Synopsis copied from IMDb - "A horror film told in three parts, from three perspectives, in which a mysterious transmission that turns people into killers invades every cell phone, radio, and television." (I must add this tranmission affects everyone differently and it didn't turn every single person into killers, though)
In first segment, the unfaithful wife is the main character who is trying to get away from her crazy husband (and other murderous people) after witnessing him murdering one of his best friends. In second segment, the husband is the main character who is searching for his wife after she escaped him and ended up staying at a nice and strange lady's house (that segment is comedy) and in third segment, the boyfriend of the wife is the main character who is also searching for her.
Fear
In my opinion it's the number two best movie about deadly obsession with "The Crush" being number one.
My Bloody Valentine (1981)
Even though I like the remake, this version is way better except one thing. In the remake I like the reason people are being killed better than the old one, even though the twisted ending has been done many times.
