Happy Friday the 13th everyone! The only to occur in 2010!
The 4th and final film in the Jason franchise (wait, what?, 8 more left!) is my personal favorite. It captures everything right about these films. You got nudity galore (including naked twins), a massive death total, and the kid; Tommy Jarvis (who is kind Dexter-like).
Tom Savini (gore maestro) came back solely for the purpose of killing off the franchise and the iconic murderer, Jason. Unfortunately, for Tom at least, this movie was awesome enough that the sequels kept coming, and coming, and coming (kinda like your Mom last night).
