Oh god dreamx, no comment on that. Im in agreeance with most of the other posts here, go in there and pick something that YOU want to watch, don't let her rope you into some chick flick, if she tries to, you can agree but pull some C and F, such as:
Her: Lets get, "How To Lose a Man in 10 Days (or something equally stupid)"
You: (give her a skeptical look and say) "I'm not a fan for that, but if you want it by all means, just don't expect to SEE the whole movie"
Too much fun, I love it
