Interstellar
Went to the theaters to watch this in IMAX for the 10th anniversary only for the power to go off & the guy couldn't rewind or fast forward to the right spot afterwards so we had to watch it from 30mins where we was originally. Not to mention there was a special needs person who was screaming the entire time.
only good thing to happen since my experienced was ruined was while the power was off people had a shadow puppet show on the screen.
