Some of the mythocritters are interesting, but they're not actually part of the KS itself and can be bought (albeit for higher prices) off the Dark Fable store already. Don't see myself backing this but I might grab a beastie or two now that I'm reminded they exist.
The mummy kidnapping set's cute in a gratuitous sort of way. Maybe combine it with the Reaper vampire with (more modestly dressed) victim sculpt and do a Universal Monsters thing? Of course I'd need wolfman, Frankenstein's monster and Creature sculpts to round out the set, and I can't think of those three lugging around an unconscious gal fig (clothed or otherwise) offhand.
