The best horror series:
Halloween - I think these ones were good for a while. The first and second one are both great. Part 3 was not with Michael Myers and was awful. Part 4 Myers was back and it was good. Part 5 & 6? So-so. But H2O was pretty good again with Jamie Lee Curtis. And then they should have stuck a fork in them. The problem with H2O is that it ignored some of the sequels. But it ended well, it captured a bit of the mood from the original and it should have ended that way. I don't recognize any Halloween movie after this one (especially not Rob Zombie's horrific version).
Friday the 13th - The first one was a classic. A very good movie and people forget it was a brilliant "whodunit". We all know the answer now, but not in 1980. No one knew who the killer was going to be. And in Part 2 it was still in doubt as well. After that, it got a little silly. They should have ended with Part 4. They just kept going though and they shouldn't have. The first couple ones were filled with suspense, it felt isolated and it didn't get silly.
Nightmare On Elm Street - The first one was excellent. After that, I have a low tolerance for the rest of them. You can only do so much with Freddy.
Saw - First was was excellent and so was the 2nd one. After that it was a mixed bag. But Part 7 did tie up some loose ends. I'm not big on gore, but I liked the writing on here and for me that was the biggest sell.
Paranormal Activity - It is an acquired taste, but I am always at the edge of my seat by the end of the film. Part 3 was the best in my mind. But they've got to start tying up some loose ends eventually. Will Part 5 do this?
Scream - The first two were epic. The 3rd one was pretty good still and if they kept it going it wouldn't have lost some momentum. Part 4 was in 2011, that was too far from Part 3 though. And I don't hear about a Part 5 yet.
Jaws - You can't beat the first one, it can never be duplicated. Spielberg knew how to create suspense and half the movie was over before you even saw the shark. It scared people. It had an impact on our culture. That's rare. Part 2 was still very good and Part 3 was alright but in a different setting. They should have left in there because Part 4 had one of the worst plots in movie history.
Here are also some often forgotten gems I didn't mention in the other thread, but just single movies.
Prom Night (1980) - A brilliant popcorn flick with a great "whodunit" story.
Terror Train (1980) - Jamie Lee Curtis again, the scream queens keeps going. Good movie to watch. Nice twist.
Hopefully I'll get a chance to see Annabelle tonight. The Conjuring was a brilliant flick.
