INSIDIOUS has a lot going for it. First off The music will get under your skin right from the get go. There's 7 or 8 scares, which is more than most horror movies i can remember, and the cast and crew do a fine job with the budget and material. There's some images that will stick with you long after the credits roll.
The main problem i had with the film is that it's so similar to Poltergeist and even Paranormal Activity. Now I've seen plenty of ghost movies, so I'm used to treading familiar ground, but it was enough to distract me during the screening. I also felt it was all so easy for the woman to come into the house and know whats going on. kinda funny even. So INSIDIOUS is well worth seeing, but unfortunately didn't reach the level of the all time classics like The Exorcist or The Shining. Therefore my final rating would be 7.5 out of 10.
