I am not the type of viewer who wants everything spoon fed as I prefer things suggested but I think in this case it's necessary. I actually think A Nightmare on Elm Street 3: Dream Warriors is better because more is explained and much more creepy.
It's the Terminator 2 of horror movies. It expands on the original, making everything bigger, bolder and more creative.
