Sounds like a fun movie. At least you didn't waste your time movie-wise. I never saw this and am waiting for it to come out on streaming/DVD. Watching this with a girl you are describing has got to be a bonus (assuming you would have eventually watched this movie solo anyway). If you are able to visit a movie theater then living with your parents doesn't mean anything much because you are independent, you can go on dates away from home, and watching a good movie is like travelling in your mind.
Did you hold hands, hug her, or whisper with her during the movie or were you both like ice cubes next to each other? Did you at least have a discussion about the movie afterwards with her and kiss her before the date ended? If you like the same movies, then at least that's something in common?
Just think you should appreciate your set-up a bit more rather than knock it down like that.
