Last year I did a movie marathon with my sister where we watched all the Elm Street movies (including the remake and Freddy vs Jason), and it was glorious. Before that I had only seen the original and the remake, so there were a lot of "new" movies to explore. I really do love the Elm Street franchise. Even in the crappier sequels, I still found myself enjoying it for the most part. Freddy is a great villain, and I even enjoyed the worst parts of the franchise as a whole. Freddy vs Jason was enjoyable, and I will agree to one extent that as a versus-movie, it did kinda work. Was it awesome? No. But I feel like both characters were given time, and for what it was trying to be, it wasn't all that bad.
Friday the 13th as a franchise never appealed to me though. I have only really seen minor parts of it. I remember seeing the remake, I've seen the one when he goes to space (Jason X?) and I remember pieces from other movies. Jason as a concept never appealed as much to me. Freddy is a really interesting villain, but a big guy chasing dumb teenagers in the forest and hacking them with a machete isn't nearly as exciting IMO. I might still do a marathon and watch through all of them eventually, because they are "cult" movies, and why not?
I would really love a new Elm Street. If it's a reboot or sequel to the remake, it doesn't matter that much, as long as they make something good. There's so much potential to make interesting dream sequences now (with special effects and technology), but if they do make a new one, I bet budget will be kept low (for profit lol) and they will try to squeeze out as much as possible from as little as possible.
I love the dark Freddy of New Nightmare and the original, but there is something unique and special with how he was handled in the sequels. I would say he is walking that fine line of being too over the top (and crosses it) in the 4th, 5th and 6th movie, but I think the third had a nice balance. To me, there was something creepy about Freddy as a character with the fact that he made fun of these kids and terrorized them, he was really enjoying "hunting" them. The fact that it was fun to him kinda made it more creepy in a sense.
