I'm a big fan of scary/haunted house movies, and I often find the house (or place) more creepy than the ghosts or any other strange creatures. It's all about suggestion and possibilities - the terror that's lurking in the shadows, paintings, mirrors. Rose Red, with its changing passages and optical illusions is still one of my favourites. The ghosts/creatures in Crimson Peak took the suspense out of it, and it didn't make much sense either, especially in the grand scheme of things. Because, well, no-one actually cared about it.
