I don't think The Disturbance deserves the high rating it's got because for the most part, it's very boring. There's more sex scenes and breasts than any regular horror flick and little violence or gore. The beginning is extremely cheesy as we see the main star falling in love, complete with cheesy music. I fast forwarded through most of these parts. He starts acting weirder and weirder as time goes on until his girlfriend says she's had enough. There is really only one part that I thought was excellent in this film and that's when the police burst into the home where the guys parents are sitting down for dinner. The parents haven't a clue what's been going on, and the man sits in the bathroom and slits his wrists. I thought this was very well done and believable, especially seeing the shock on the parents faces. The film starts to look sort of "good" after this, as the man is put in hospital and we realise what's actually been going on, and why there was a distinct lack of gore and murders. The trouble is, it comes far too late to save the film - by this time you will be bored to death. The concept is good and it's a good look at insanity, but it should have been more interesting from the beginning.
I wouldn't recommend this unless you're into films that take a peek at mental illness and insanity. It's not really for horror fans.
