I just watched The Omen (1976) for the first time last Halloween. I wasn't completely blown away, maybe because it was a bit dated, but it is definitely a classic. I haven't seen the remake so I can't compare, but in the original the kid and the dog freaked me out.
Warning, Spoiler:
The scene where the dude is beheaded by the giant piece of glass was awesome. I wasn't expecting that at all.
