Not the most amazing sound or picture, but decent. I saw Spiderverse here twice and it was good. That being said, the A/V is still solid, which is good to see, as that's what you don't want to cheap out on. These standard showing theaters are a little cramped and poorly designed. The seating is also low on legroom in these theaters, so people behind you can end up kicking your chair or whispering loud enough for you to hear.
The standard showing theaters have non-reclining brown leatherette chairs that are honestly a little uncomfortable, but not the worst.
