I know the studios are taking a hit because of theater closings, but dang! -- $20 to RENT a movie? It would only cost me half that much if I saw it in an actual theater!
The movie won't cost $20 to rent if you wait until after the theatrical run would end. You're paying a premium because it's a currently-screening movie.
Given the average household size, $20 doesn't seem unreasonable. Especially since you get to bring your own popcorn.
