Call me weird, but I've always loved spoilers. When I watch a movie on TV I've never seen, I'll quickly go on-line and look up the plot (wiki is great for that). I'll read it to the end, and then I'll sit and watch the movie to the end and, for me, it doesn't harm my enjoyment one bit (quite often it enhances it, especially if the film is rather difficult to follow because of twists and turns). Plus, I'm actually good at figuring things out. When I saw The Others, a creepy, atmospheric ghost story, I figured out the ending. When I watched part one of season two of The Walking Dead (currently my favorite TV show), and they talked about a "shocking" final scene, I figured out what it would be episodes before it aired. So, for me, hunting down spoilers doesn't take away the fun; often, I've figured out how things are going to go and end even without them. I already have an idea how DS-the-movie will end, but I won't say here. I'll wait until after I've seen it and let you know if I was right.
