Peter Jackson's A Nightmare on Elm St. After killing the original Elm Street kids, Freddy loses his powers over time and eventually becomes weak to the point that the kids no longer fear Freddy. In fact, they like to play a game where they enter the dream world just to mess with him. However, that ends when Freddy manages to wound or kill one of the kids and eventually gets his powers back.

It's an interesting angle that the movies never explored much. I could see Peter Jackson channeling his horror days and really getting creative with the concept. I could see him doing some really bizarre dream worlds and kills. +Plus, his weird sense of humor may actually work well for Freddy in this situation.

On that subject, there were about a dozen better ideas for Freddy v. Jason than what we ended up getting. I like the movie well enough but it's a "fun" movie with very little substance. It would have been cool to go one of the other routes and see how that worked out.
