Le Sous-sol de la peur

I really think people who describe this as a comedy or even a horror comedy are missing the point - it's a classic fairy/folk tale, right down to the theme of the kid having to earn manhood and a "real name" by doing a heroic deed. Wicked step-parents, hidden treasure (gold coins, even!), creepy house with secret passages and monsters in the basement, captive maiden to be rescued, innocent villagers held in slavery by evil (land)lords - it's all there! I know this could be said of a lot of fantasy/horror films, but this one seems to be more clearly derived than most. Loved it!
