I know there are smarter ways to invest your cinema money, but I checked how much I could spend in a fancy cinema in Munich, Germany for the OPs experience and came up with 19€ per ticket (balcony plus a popular superhero movie), plus 16€ for a (big) popcorn and two drinks, for a total of 54€ or ~USD 63.

I agree that the average experience could easily cost half that, but the point of how expensive cinema can be (imagine adding a second popcorn or, God forbid, nachos!) is a good one.
