Lel. It didn't make much sense. I'd rate it a 9/10 on gore. 10/10 for blind shooting. 3/10 for plot line (Mmm, plot). 1/10 for being a sequel (isn't actually much of a sequel, bloody wankers). 8/10 for some love making time. Lel.
You know a film that is kinda ass? The original last house on the left. Maybe it's the fact it was like the 70s where they couldn't really work much with gore and shit, but it just didn't feel much like a horror film.
