Yeah, I totally dig the Shining, even the 1997 mini series was extremely well done. It's just a classic ghost story that you can't beat.
I also enjoy the original Halloween..probably because it's one of the few in the series that I'd consider more psychological then 'slasher.' However, after H20 came out I think it replaced Halloween as the greatest Halloween movie ever.
Burnt Offerings...yeah, sometimes I forget just how creepy that movie is until I sit down to watch it. It probably scares me worse than Audrey Rose. The end scene was totally unexpected and horrifying. I was very young when I first saw it and didn't even really comprehend what was happening, which scared me even worse...LOL! It's on DVD now, you should pick it up.
How about demonic car movies? Christine was pretty good, and 'The Car' was pretty scary for its time despite its corniness.
