Why stop here?
Let's make it socially acceptable to talk too, it's just a bit more annoying? Or sitting down -- what if you and your friends can't talk as a group sitting down? Walk around and talk to other people.
Then all we need are remote controls for the majority of the older, male patrons that will let them endlessly flip through all the different movies playing.
A positive suggestion -- adding a "L2" warning to movies that require an attention span of longer than two minutes.
