I watched it all, well except for the boring parts. It was better than most horror movies, but it wasn't really scary. But hey, I watched, The Exorcist, when I was 16 back in 1976, then went out on the lake around midnight frog gigging afterward.
1 star: couldn't watch more than 15 minutes. Unwatchable!
2 star: jumped my way to the end for the ending. Unwatchable, but interested in how this turd ended.
3 star: watched it all, but not happy about it. Nothing better to do.
4 star: I watched it, liked it well enough. Would never watch it again.
5 star: Great moving picture show! I'll watch it again, and maybe again in a few years.
