Pivoting for a moment from Sandy to Samhain: don't know about you, but my favorite Halloween film - from the same-named franchise, at least - remains 1982's Halloween III: Season of the Witch. An occultist toy manufacturer, pissed off at the secularization of the holiday, imports inherently demonic slivers of Stonehenge, imbeds them into microchips which are sewn into jack-o'-lantern masks and triggered by calliope music (and wildly oscillating, mimetic 8-bit graphics) to crush the skulls of children and turn their bodies into seething clumps of crickets and garden snakes. A great bloody HUH? of a movie.
So, put on your Silver Shamrock masks, kids, and good luck!
