For "other" I'd like to add poor technical quality. I've been to more than 5 movies in the past few years where the surround sound has cut off along with the sub, rendering it basically in mono. I distinctly remember this during the third Matrix movie, which wasn't great, but I wanted to enjoy the rumbling.

I got up and complained to the theater manager. He kinda looked bewildered.
