Well....
At some points it diden't feel like "Friday the 13th" (Jason would not just stand there, he would of gutted her like a fish in 2 seconds) I don't think you watch the series too often. Most of the killings were swift... Just watch a couple of the movies next time you do a movie with jason in it. Sure, you can do the same thing that you did in this one, just don't fuck up jason.
(If you have noticed already I am a really big fan of horror movies)
All in all the movie was well done... I did wish there was some voices but hey what are you going to do?
