I think it's possible that it will turn out to be a "..and then he woke up" movie. At this point I'm intrigued, and I don't want to know too many details about the plot. Just some overall info from reviews to know if it generally will be worth my while.
I also haven't seen Ari Aster's previous movies since "horror" movies aren't my thing. But I know that they were very well received.
