I liked it. It's a nice old-fashioned (flawlessly 70's styled) slasher horror-flick, with a fairly original premise. As in any comparable horror movie the motives for the killings are pretty farfetched, but who cares, when they are pictured so relentlessley gruesome, the gore here is definitely not for the tender-hearted. Another strong point is how the movie very gradually builds up the tension, this is a real slow burner, the apprehension of looming doom is palpable throughout the movie. This is helped by a strong direction, a very clever and inventive editing, and some great photography, see for instance the scene of one of the girls swimming in the lake, while... well, I won't give it away, but it's beautiful and hair-raisingly scary at the same time!
Add to all this some very funny dialogues and goings-on at the start, and you're in for a well made, old-school horror flick, maybe not life-changing but absolutely entertaining for those who can apprciate this kind of movie (like me!).
