Sure, it's not the best horror ever, but nonetheless, in a non pretentious way, pretty enjoyable. There's the well known premise of a bunch of college kids stranded in a remote villa, and then a masked killer starts hovering round the house and slashing one by one, up until (of course) a last one standing. They did put in a few nice plot twists, like the identity of the killer that I (stupidly) hadn't seen coming at all, and another surprising one in the end, keeping you on the edge of your chair until the credits start rolling.
The acting is just so, so, but in this kind of movie: who cares?! All characters are equally unsympathetic, so you couldn't care less what happens to them. Which is quite a lot, since they didn't hold back on the violence and gore, with pretty original killings, it's definitely not for the tender hearted.
If you want deep dialogues and impressive cinematography, you'd better skip this one; but if you're in for some 80 minutes of pleasant old school slasher fun, you won't be disappointed!
