Yes, this is definitely one of the best. I agree about "The Crack in the Wall," and I would put "A Horror Story" and "Hickory Dickory Doom" up there as well (except for the terrible sound on my copy of "A Horror Story").

By the way, not only is this one reminiscent of the Omen, but also of an old Mysterious Traveler episode from 1944 entitled "The Good Die Young." It's probably available on the web, for those who liked this CBSRMT episode.
