It's nice that she came to see it with you in the first place, but it's really shitty of her for making her distaste of the movie known to you the entire time. I don't know how much of this she was doing, but snide comments like "ugh... really?" during scenes that you actually like, is detrimental to your experience as a whole. Just tell her that you would rather watch movies that you're looking forward to without her due entirely to the comments. She'll get pissed off at first, but too bad. You have the right to enjoy your extracurricular activities without having to constantly look over and see if you're allowed to like something.
