I always think copy n paste is not a problem. Even this movie is just like one of best tv drama ever - Dexter, but it got its own good. The bloody scene is a big plus given it's a horror, real horror. The actor behavior is explained clearly by his childhood encounter which audiences are convinced. Only little bit is not convincing is the job of the killer is a counselor. His look is too gang member kind or rough man but not look as soft as be a counselor in high school. If I'm a student with problem, I will cry out when seeing this type of counselor. Only this part I not buy.
