OMG - YES! How could I forget about that silly little film?

The Backwoods (Sera, 2006)

More descendents...
 

Thanks for the list Ferox, I'll be checking those out and adding them to the list shortly.

Papillon Noir - The Backwoods (Serra, 2006) was incredible all the way through, though I'm not sure how to regard the ending. Has anyone else seen this film? It fits the classic Urbanoia mold, but the ending was highly ambiguous. A comment on cultural difference? I don't know.

Nothing But Trouble.

Again. It fits.
