I've always found the "you don't have any power over me" portion of the ending to be a little lackluster. That's always been the appeal of Freddy as a monster, dreams are uncontrollable and you're just along for the ride. Your mind can terrify you while you sleep for no apparent reason, and all you can do is wake up in the morning and shake it off. The Nietzsche quote at the start should be the ending tone for flavor continuity, and that's something I like about the car and kids - the ground falls away.

The ending might be a little heavy handed, but something leading us to believe Freddy is still lurking on Elm Street would have been a sweet spot.
