Insidious. Possibly the most un-scary horror film ever. Rushed, cliche'd plot regarding a possessed child / house. No atmosphere or build-up of suspense. Stock genre characters include the freaky kid who knows too much, the paranoid mother, the disbelieving father and the strange old-biddy spiritualist woman. The climax was ridiculous.
I watched this with a few mates. The only scary bit was when the host Becks got her kids to charge into the lounge in the middle of the film dressed as pirates, wielding plastic swords. That DID make me jump.
Horrifying, but not scary. Laughable, but not funny.
