There are lots of amazing horror movie series and lots of really bad ones. I think the best series is Friday the 13th by far. Among other good ones are Halloween, Texas Chainsaw Massacre, and Scream. F13 was probably so amazing because of the classic kills and of course the villain, Jason. Out of the F13s I think that Part 3 was the best. It was the one where Jason began wearing his signature hockey mask.
But what do you think the best is, do you think it's F13, Halloween, Scream, or something else?
