This really could have been an all time horror great. I stand by that, even 10 years since its release, it still sticks with me as one of the films that was nearly brilliant. Focusing the rating down has been hard and one that changes every time I think about the film. It is held together by a nearly perfect plot, well the first 3/4 of the film. Unfortunately, the end is what let 'Insidious' no better than the rating I have given it. Don't get me wrong, I like the film. The first time I saw this I was 12 and I was on the edge of my seat. But then it got to the finally quarter of the film, and I lost that enthusiasm. I think the Darth Maul lookalike character really ruined what was a revamp of a traditional horror and thriller. Following the crazy story of a family who are all, to some extent, influenced from what initially feels like paranormal activity, the vast majority of the film leaves you curious. The loss of flow is unfortunate, it really is. I wish I could have enjoyed this film more but, ultimately, the ending killed it. I am yet to see the follow ups, and I look forward to seeing whether or not they patch over the flaws in the first feature. One line stuck out to me first and has done ever since is "I don't like when he walks around at night", certainly playing on the traumatic childhood fears of someone else being there that nobody else can see. It really was so close to hitting the mark.
