Micronaps where always a part of Freddy movies. Whenever a character finds themselves in a dream, despite being someplace where they wouldn't normally be sleeping, they were essentially taking a micro nap. They just never really gave it a name in the original movies.
The Friday remake wasn't really all that great. I mean it was nifty, but I didn't feel it offered anything worthy of a remake. The kills were so so, and the plot just meh. I liked the idea of the underground tunnels, but overall it just seemed like it was a generic slasher that just used the hockey mask to make it an official Friday movie.
