Abso-freakin'-lutely.
The couple with the infant at the 9pm showing of GI Joe this passed summer seemed to think that their child SCREAMING bloody murder for the first 20 minutes of the movie was NOT a disruption. Apparently nobody else in the theatre thought so either, because nobody said anything to her. It was MY opinion that the kid was a disruption, so we got the manager and he kicked them out.
YMMV.
A better resolution than calling the child a name.
