Indie movies are absolutely notorious for their habit of appealing to low intelligence people, it's practically their main market. They don't have much budget to tell an interesting story with, and are often being written by grant funded people without much experience and who are just desperate to make a movie (any movie) so they end up relying a lot on faux depth and complicated BS to make the movie seem like it has more to say than it really does. Critics lap that stuff up but most people who just want to be entertained with a risky but well made idea that doesn't puff itself up, the bigger studios are where you'll find them.
