The whole trilogy over a few hours was a chore. They turned off the air-con, presumably so everybody there could experience their own Summer of '72 in New York. I hear it was really fucking hot so people went the cinema and stuff.
Same problem at our local flicks. They must've made a rake in drinks and ice cream sales that night.
More annoying though was the moron sitting next to me who insisted on quoting aloud lines several seconds before they were spoken, all the way through SotD and HF. Not even punchlines, just small bits of expositionary dialogue.
Did you watch it at a Vue cinema?
