I actually think the more "obnoxious", or rather "active" the audience is, the better. I can multitask enough to pay attention to the movie, and a lively audience adds to the entertainment for me.

I remember when a friend and I went to see The Sorcerer's Apprentice at the cinema, and there was group of kids to the right of the row in front of us, and they were reacting aloud to things, and they were funny to hear at times - so it added to the entertainment.

Two highlights were when the Fantasia music played, the kids all cheered, which was heart-warming (see, kids do like things before their time!), and before the movie started, there was a short-film which was quite strange (I can describe what I remember), and the kids were reacting to that as well, but at least one of them thought it was an advert, because when the credits came up, she said "That was a film?!" It was funny.

So yeah, I'm okay with it.
