Last House on the Left (original) was clearly influenced by the culture and that era so has dated poorly in some ways. Like Kong 76 which wallowed in the apathy of the post hippie dream
Jason and Freddy hold up because they deal with timeless themes. Boogeymen and Nightmares. Transcends any one era or culture. I could go all Joseph Campbell on those films. There is a sense of an anti-hero's journey with a lot of the great horror icons.
Mmmmm....are they really timeless themes, or did you just love them when you were a kid? I at least have the humility to admit that my love of Freddy Kruger has more to do with nostalgia than film quality, I mean yes the theme of being haunted by inner demons or dreams is timeless...but Freddy Kruger was a child molester who made sexual jokes, those films are fucking sick, and I just marvel at how popular they were in the 80's-90's...but people honestly think society has gone down hill? That eleven year old girls are more in danger now? I do love NoES though.
I have always hated Jason, I think the Friday the 13th movies are absolutely boring and stupid after the first one, and I like slasher films like Black Christmas 1974 and made sure to watch the reboot, as well as both versions of My Bloody Valentine, and some of the lesser known or less popular ones like Happy Birthday to Me, April Fool's Day and The House on Sorority Row...a lot of that stuff is about atmosphere, if you like the style of say, Dario Argento or Tobe Hooper, or Brian DePalma, you might just continue watching films in that style for nostalgic reasons.
The Exorcist did scare me and I still think it's one of the better written horror films. I agree Last House on the Left is era specific, but most horror movies are (our generation is obsessed with disease/HIV in sublimated forms and "zombies" in the various mindless forms that can take) ...my ex loved that one, it was one of his favorites, though I never liked it.
Horror movies are pretty subjective, I almost wonder if it has anything to do with MBTI preference. Some people can't watch them at all, or can only watch "horror lite" like Donnie Darko, Frankenstein, or kids movies like pretty much anything directed by Tim Burton.
The original Texas Chainsaw Massacre is a work of art to me, but I find the original Halloween films so-so, and I think Rob Zombie gave them an intensity and character development they previously lacked. I think he's a hyperreality artist, like Park-Chan Wook's Sympathy for Lady Vengeance, that sort of style, either you like it or you don't.
Alice Sweet Alice from the 70's is a great cult film, and so is Night of the Demons from the 80's - though they have completely different feel. Alice Sweet Alice is like an Italian giallo, and Night of the Demons is almost pure cheezball fun. There's something about that "self-conscious" horror that I love though, like Night of the Demons, Rob Zombie does that too.

I saw ouija this year. Pretty good.
The little girl is a good actress, I enjoyed it. I thought it was a better sequel than Conjuring 2.
