Can think of a few off the top of my head some which no doubt people will agree on and others that people will probably slag me off for.
Funny Games US bored me to death. Cube whilst an interesting idea lacked any kind of suspense thus it was boring. And now for the two that will likely make me a hated man. The Blair Witch Project, I found it so completely boring and void of any suspense sorry but a few scruffy idiots going into the wooRAB and then jumping every time they hear a noise is not scary. And probably the biggest shocker as so many say it is the best horror of all time The Exorcist, I have watch both cut and uncut versions and was not the least bit phased by them. No scares at all, in fact I found myself laughin at how badly funny it was.
