It's unlikely that you can judge how scary a movie is completely objectively. If you watch Freddy Krueger on TV through an old CRT TV, where there are ads everywhere, the sound quality is terrible, and the TV is usually not turned up as loud as you'd like, then you're in for a viewing experience with a few exciting moments, but nothing truly terrifying.
If, on the other hand, you take a more or less modern movie (like the aforementioned "The Ring"), sit in front of a huge plasma TV on a couch, surrounded by a $10,000 home theater system turned up loud (loud enough to make the neighbors' chandeliers shake, although you can turn it down a bit), then I can guarantee that watching it will give you more pleasure than watching the same movie in a regular movie theater. Of course, the first case is too pathetic, and the second is utopian, but you still need to understand that the viewing conditions can play a bad joke on a truly scary movie, turning it into just a beautiful production.
Ah, but "Nightmare on Elm Street" always has a good plot, and what kind of tricks does Freddy pull off:D... Especially in the sixth one, where he initially portrayed the witch from "The Wizard of Oz" (for Americans, it's called that:D), and then how he killed that deaf guy:D, although the way he killed in the game was the funniest:D.
I'm being honest, watching old favorite horror movies like "Nightmare on Elm Street," "Tales from the Crypt," or "Night of the Demons" is just a pleasure:). And all with the same good quality and sound)) Yes, I watch these kinds of movies, so don't throw popcorn and slippers at me:D.
P.S. And "The Ring" isn't scary at all, it's just mesmerizing:D.
