Complain about the quality of your local THX-certified cinema here! Lucasfilm will give them a nasty call and send someone over to straighten shit out.
I know Singapore’s Cathay Orchard Cineleisure multiplex is on my shitlist. Movies there are often played way too loud (and it starts from the commercials, so you know it’s going to be one of those days. Technically, this gives me ample warning to go outside and complain, but I’ve done enough of that and I’m sick of it. Now I can go straight to the cops.)
