Today I went to see the movie with my family. I was at the point when the kid is singing and was thinking that the movie was pretty good, but not great yet, when a guy in the very back of the theatre yelled "DIE" as loud as he can. His friend quickly said "dude not cool" but it was too late, the movie was ruined for everyone, a kid started crying, and everyone started giving him (and me in a case of mistaken identity) dirty looks.
How could someone be insensitive enough after what happened to do this in a movie theatre?
I've been told he did this about the same point in the movie the massacre began.

I later became immersed in the movie, but others were visibly upset.
