I worked at a theater in high-school/college. I think it was Dark Knight, but at some point after going digital they brought back the film projector for certain shows and it was presented as a quality thing. I’m a super auditory person, so the thing that always stuck out to me in the IMAX was the sound. Those subs bump hard.
Conversely, one of my worst experiences, subjectively of course, was HFR (high frame rate) movies. I think it was a LotR film, but it looked so weird that I couldn’t get lost in the story.
