And to that I say- BAH!
The movie was ruined by all the shit that was going on anyway. Adding to it made no difference. Especially since only the people around me could hear anything I said cause I was talking to my friend. It was a fucking matinee (or however you spell it) for a children's movie. No one went expecting to be able to sit and watch the movie without all that shit. The only reason anyone even singled my friend and I out is cause what we were saying was offensive to fans.
In different circumstances (as in a night showing of a pg-13 and up movie) though, I definitely agree with you and it's rare that anyone over the age of 8 does anything to piss people off.
