I'm 45, and a massive Ghostbusters fan. But all it is, is a super fun zany romp. There's nothing else of any meaningful substance. No major character arch's or touching moments of humanity. Nobody reflecting on the nature of "living" vs "dead" if it's all just different states of being. And the movie is certainly no worse off for the lack of it. In fact adding more meaningful scenes or concepts to it would probably make it worse.

A lot of people seem to believe a "low substance" movie is synonymous with being a bad movie. It's not.
In my mind "Style" is entertaining and "Substance" is meaning. Ghostbusters and the rest of the movies I listed are all about only being some form of interesting entertainment. They're lacking in any other real message, meaning, or point. (Or making it so unintelligible as to be meaningless) Some of them are very popular movies. Movies people don't realize have no actual meaningful substance. Others are not. I would argue they're all good at being the movies they want to be, and recognizing that sometimes substance isn't actually worth anything.
