Parents

It's been 13 years since I saw this movie, but it made such an impact on me that to this day I can close my eyes and visualize the characters, and feel the mood that make this film worth watching. Not too many movies scare me like this one did. It wasn't the use of vast quantities of blood, or the killings that scared me, as much as it was the Ward and June Cleaver-ness of the parents. What really did it for me was the mind twist the director built into this film, and the way it was pulled off by the actors. If you're squeamish then this probably isn't for you, but if you can watch a movie and appreciate it for the art it is, I recommend it.
