I just watched all the Nightmare on Elm Street films, so you bet I'm going to rank them.
9 - Final Nightmare: good lord this was rough since by this point it had just gone full on Loony Toons and Freddy looks more like an old woman than a terrifying dream demon. The video game sequence is the absolute nadir of the franchise, so bad I felt embarrassed for the people involved.
8 - 2010 Reboot: going to be honest, I didn't rewatch this one as I saw it not too long ago. Plus it was yet another mediocre, pointless remake that I don't want to watch again. Freddy's actor did an ok job, but it looks like he's covered in melted cheese and some of the effects are somehow worse than the original.
7 - Part 2: well this is certainly the most disturbing film in the series, but not for the way they intended. Half the film is spent leering at the male lead, Freddy possessing people is a decent idea but made pointless when he just appears in the real world anyway, and the bird scene is more comical than scary. Freddy himself is about the only redeeming feature here.
6 - The Dream Child: better than I remember, with the chemistry between the cast ensuring that it doesn't gets dull. It does look like a music video and Freddy doesn't do much besides spout one liners and laugh manically, but a watchable entry nonetheless.
5 - The Dream Master: some good kills and well shot, even if it is starting to get a bit formulaic and it's clear they're making them because Freddy is popular rather than an artistic decision. Of all the films I'd perhaps have the least to say about this one, so didn't do anything especially bad and can rank in the middle. That's the disadvantage of watching so many similar films in a short time frame.
4 - Freddy vs Jason: technically shouldn't count, but I'll never complain about rewatching it, because the film makers knew the audience just wanted 90 minutes of 2 horror icons smashing the shit out of eachother. And that's what we got.
3 - New Nightmare: always felt this doesn't get the attention it deserves, it still feels fresh and original, whilst definitely laying the groundwork for Scream. Nice to have Freddy back to just being out and out evil as well and I really like the depiction of the dream world at the end. It is a bit overlong with a few too many exposition scenes, but other than that, solid.
2 - The Dream Warriors: remembered as the best of the sequels for good reason, since it feels like it continues the original story in a logical fashion. Even if the effects have dated the kills are still inventive, the characters engaging and it's just an all round fun watch.
1 - A Nightmare on Elm Street: never any doubt this would be number one. A certified classic dripping in atmosphere, with the natural advantage of being the first and thus trying to hide the killer for much of the film. The fact that a lot of the effects and kills still hold up only enhances it further (well, except the blow up doll at the end, but can't have everything.)
