4 Really, really creepy.niceguyeddy | 06/05/2011 | See all niceguyeddy's reviews (17)As I said, genuinely frightening. It has a pretty decent plot, but what's more important is that it has a perfect mix of tense moments and jump scares, and the use of old-school horror strings over the credits work perfectly - at the start it sends us instantly into horror mode.Insidious is only marred by one certain 'workshop' scene (in my opinion) which gave the film the 'Jeepers Creepers effect' (copyrighted phrase :]). I don't want to give away the scene, but if you've seen both films you'll probably know what I mean.I love horror movies, but I hardly ever get scared by them. I'm not trying to sound all macho, it's just that at worse I usually get a little freaked out then forget about it. Insidious and Paranormal Activity are probably the only two which have given me a hard time getting to sleep right after watching. And if that's not enough to prove that it's scary, I discovered I have marks on either side of my chest from grabbing so hard during the tense moments!Fans of horror, take a look.
