This kind of situation is why the Founding Fathers regulated interstate commerce to the government.
It does not solve the problem at hand: the problem of rude patrons. Rowdy brats, loud commentary, and so forth will still be problems. Last time I went to the movies, my experience was ruined by someone who aimed a laser pointer at the screens for 30 minutes. No one did a thing about it. You want someone to blame--blame the eunuch management.
A movie theater is so totally not "interstate commerce", I can't imagine what connection you see.
