Friday the 13th

In a full moon night of a Friday, 13th, the instructors of Camp Crystal Lake are murdered, one by one, in a night of terror. In the end of the story, a convincing explanation clarifies what have happened. This cult movie was very original and spooky in 1980. Placed basically in one location and with unknown young actors and actresses, it was indeed a successful low budget movie, copied many times in other films. Today I have just watched it again, now on a recently released DVD, and it is still good to see. I regret the sequels, since the story is very well resolved in a credible way without supernatural. This way, it is much more terrifying and could have stopped right here. My vote is seven.
