As Halloween approaches you should mix in a creeping looking demonic kid into your viewing schedule and The Omen will work just fine.  Make sure you watch the original 1976 movie starring Gregory Peck, not the horrible 2006 remake (also keep in mind that as far as the sequels The Omen 2 is watchable but they get worse and worse from there).  I was young when I saw this and that kid and the music still creeps me out.  Enjoy official trailer and then get out there and get the film!
