"Dreams in the Witch House" from Showtime's "Masters of Horror" anthology had much better press and production values, but what about "Crouch End" from TNT's "Nightmares and Dreamscapes: From the Stories of Stephen King"? (On DVD if nothing else.) I think Crouch End veers closer to Shadow Over Innsmouth in flavor, but casts a woman (Claire Forlani!
) as the main protagonist. Less "scary" but rather visually interesting, plus it's fun to watch Forlani WIDE-EYE everything as a simple visit to a New England town goes horribly wrong. Variations on several Mythos names near the end.
Come to think of it, the whole tale could totally emulate how King would write up an Arkham Horror Session Report...
