Yeah, but it is still a bit of fun which these movies turned into. The first Nightmare film is my favorite horror film - it's superb on so many levels.
The first Friday the 13th is good in it's own way, relying on gore and jumps primarily - I do think Mrs Vorhees is a better killer than her son LOL. THe Friday the 13th films have always appeared quite cheap I feel - though Jason, like Michael Myers creeps me out. They're fun to watch, but that's about it, except the original - I like that one.
