Query: Good Idea, Bad Execution

The premise of this film pretty much sells itself: uber-hottie du jour Megan Fox plays a cheerleader possessed by a demon. But that's about it, at least for me; the story they tack on to it was rather weak. My main problem is that this film is told primarily in flashback, which pretty much dilutes any sort of tension. And then they didn't really take advantage of their selling point. This thing could've easily been ramped up into high camp, much likeGrindhouse Presents, Planet Terror - Extended and Unrated (Two-Disc Special Edition), but it fell far short of that. Oh well...
