Yeah, I really enjoyed Freddy Vs. Jason, but it is a little difficult to follow that up, since they didn't know what to do in the sequel, like have Ash from the Evil Dead series, or add someone else like Michael Myers. The end of the movie was a little confusing too, as it showed that Freddy is still alive, but I don't know what the hell he could do at that point, with his head chopped off and all.
He can just go back to living in Dream Land where he has his whole body.
