What is the most annoying/distracting thing when seeing a film at a cinema?

[Girgi Girgin 38]

People who are on their phones... Kids crying... Like, sometimes parents are dumb enough to bring their small child to either a super graphic film or what have you... 

[Penny 128]

I cannot stand people kicking my seat or talking. I don't care if you are playing a game on your phone, or making out in the back of the theater but just don't kick me or talk constantly through the movie. I did not pay 12 dollars to hear your commentary or to gain a backache.

Babies in the movie theater. I really don't wanna sound like a jerk but damnit if you can't find a way to keep your crying baby quiet then don't bring them. Why would you bring a baby to a movie theater anyway?
