Perhaps the problem is that they were both concerned with their own needs and desires and were unwilling to consider the other.
F'rinstance, wasn't there any discussion about what movie to see? Why on earth go to see a movie she clearly disliked? You got kicked out the first time (and remember, crash, they didn't pay for this movie as was directly stated...they sneaked in.) Why on earth were you two going back to see something one of you clearly had a problem with?
If she wouldn't be quiet, why wasn't she politely asked to be quiet?
And yes, I find it highly rude to ask somebody to leave the theatre on a personal request that can be accomplished on one's own right at a climactic scene. And if she was truly detesting this movie, one would think she would have jumped at a chance to leave the theatre in order to get away from it.
It seems the two of you didn't like each other and this movie simply became a way for the two of you to make it crystal clear that you didn't.
