Ask HN: What makes a great movie theater experience?

If you're someone that enjoys seeing seeing movies in theaters (and are reading this), I need your input.

I'm working on a side project - and am looking to create a list of the most important factors that go into making a great movie theater experience... great.

Things like:

- Screen size - Sound quality - Popcorn quality - Bathroom cleanliness - Seat comfort - Bonus offerings (food delivery, bar etc)

What would YOU say you care about most when visiting a theater? Any thoughts / feedback would be greatly appreciated.

BONUS: What are some of the nicest theaters you've visited where you live?
