I completely agree, guys. Jackholes who leave their cell phones on and text (or worse--TALK) while the movie is going, really piss me off.
My cell phone gets shut off once the lights go down and the trailers start showing.
But again, for the most part, I've been pretty lucky, even on opening nights. My worst experience was Alien Vs Predator: Requiem....and I've spoken ad nauseam about that night. But since then, it's been reasonably good.
