Just did this tonight. Same movie.
My friend and I figured it would be fine because it was the middle of the week, and it was a subbed anime movie so figured there wouldn't be too many other people around to worry about. Definitely felt weird being in a theater, but there were only like 8 other people there and picking the seats cleared out all the seats around what you picked with ours as well so didn't have to worry too much. Was really fun though. Have definitely missed going to the theater.
It was in South Dakota so I was worried they would half ass some of the typical protections, but the theaters there are doing a good job at least. Figure it's probably mostly the businesses that are nationwide that actually bother doing anything. Most of the stuff local to that state not so much from what I saw. ?
