You might have Misophonia: https://en.wikipedia.org/wiki/Misophonia

I do agree that crinkly candy wrappers and noisy chips in a movie are annoying, but not extremely so.

But I do get irrationally angry when people talk during movies - to a degree that makes it impossible for me to watch MST3k[0] at all. I like the premise, the jokes are funny etc - but I just can't tolerate people talking over a movie :D
