Do not worry about it, maybe you are been a little oversensitive to the situation, after all, it is just a movie you were talking about and not real life. Did they really excuse themselves because of the way you were talking? I doubt it and even if that was so, it is just a movie, they won't be mad at you about it. People don't always want to listen to me babble on about my passions or hear my opinions, I do not take personal offence to that and neither should you. Don't worry about it. I personally cant stand star wars, i would not want to listen to anyone critique it, I don't care for it, I would have excused myself from that conversation before you joined in., nothing wrong with that is there. Don't worry about it.
