I like more of the old-school horror flicks. Crap like Saw and (fill in the blank) are cheap slock.
I agree--I avoid movies named for tools: saw, chainsaw, pliers, pruning shears, nutcracker.....
The best horror film ever was the original
The Haunting--no ugly monster, no blood splatters, no silly special effects, and nothing jumps out of the dark at you; just a well-told spooky tale that lets you use your imagination to scare yourself.
The original
The Thing From Outer Space also was well done, well acted, and made good use of suspense instead of gore and the cheap thrills of boogie-bears jumping out of the dark. And it avoided the usual cliche of the expendable cast member wandering off to a horrible death after everyone was told to stick together.
Someone else mentioned
Psycho--a good story, well acted, but to my mind more suspenseful than horror. After all, it's the story of a mass murderer--an unusually nutty one, but still a mass murderer, albeit one who kills only when someone comes into his world and throws it off center. Unlike Zodiac or Son of Sam, he doesn't roam around searching for victims.
