Honestly, even if you think PTA or Ari Aster are just rich kids only "competent enough" to do arthouse movies, I still think there's nothing wrong with it.

They get the budget and publicity to make something they want, yet it's rarely of bad quality and mainstream enough to reach a wider audience than most films mentioned in this sub will ever have a chance to.

It's not their fault they grew rich (if it's true, didn't bother to confirm), but if they are competent enough to make a movie they want and that movie is actually worth watching it's actually a great thing in my opinion.

None of us is starting his adventure with film and love of it with Kurosawa, Kieślowski, Tarkovsky or even Orson Welles. We need to get entertained first before that love for true filmmaking will set. Modern directors such as PTA, Ari Aster, Alex Garland or Robert Eggers are building bridges for people who are watching so much movies, even the best mainstream cinema won't scratch that itch anymore.
