Friday the 13th is your typical slasher movie except for one thing... Jason actually appears to be human in the sense that he has to chase his victims to kill them rather than just appearing out of thin air like he did in past movies.
There are a few *surprise* scenes as seen in the trailer, for example, the shower scene. It was awesome!
I really enjoyed this movie and it was everything I expected and more. I recommend it to any horror fan who enjoys these types of movies and can appreciate it's entertainment value.
