... Not really a problem I have. I enjoy writing, I enjoy watching movies - the two go hand in hand... and inevitably, I make lists of movies I want to see, movies I may see someday, and movies that feature actors I like but that will probably turn out horrible.
I'd rather other people see my lists, than just hoard them for myself (Though I've always cataloged them for my benefit). If you can find a hidden gem, or something worth seeing someday, then they've served a purpose. Obviously, these will grow over time, and I intend to link 'em in the sidebar!
