It's also pretty zany and seemingly random at times. Some people just don't want that in their movies. Some just want easy to digest entertainment, and this movie does get pretty densely packed, requiring concentration to digest it. My parents didn't like it.

I loved it for the very reasons they didn't.

So I get the reaction, even I think they're missing out on so much of the film as a result. In fact, I don't personally know anyone that liked EEAaO, which is also true for The Batman. It's weird, because I used to share a lot of common favorite movies with friends and family, and then a fairly sudden divergence across genres.
