Looking for movies

I'm never too excited by most online quizzes and surveys, even though I admit they do add a nice visual element to people's LJs. However, none have really caught my fancy lately, so I've decided to start a little pastime of my own, one in which all my faithful (what - 6? 7?) readers can help. I'm looking for really interesting movies to watch, and given that there are thousands to choose from, I need help narrowing it down. So, here, for your amusement, is the list of all the movies that I have rated 10/10 at the Internet Movie Database. From this list, I hope someone out there will have some suggestions as to some other movies (especially ones that are more obscure and that I may not have heard of) that might suit my (admittedly very dark and morbid) tastes. Obviously, if a really popular movie or one by a director I obviously like isn't listed, it may very well be because it got an 8 or 9 out of 10, so it probably isn't very useful to list all of the movies of, say, Kubrick. On the other hand, if you know something that's quite obscure but seems to fit, I'd greatly appreciate a heads-up.
