Everything Everywhere All At Once is hard to describe. It's not an art film, per se. It's sort of a comedy, sort of science fiction. It's philosophy, much in the way The Matrix is. It's a story about parent-children relationships. It's about information overload and growing up on the internet. It's psychoactive. It's... an accounting thriller?
Philosophically, it's fundamentally an argument against nihilism, with absurdist influences. As hard to describe as it is, it's also hard to spoil. EEAAO is about the journey — and it's not short.
I don't add many movies here, but this is probably my favorite movie. However, it doesn't hit everyone equally. It requires a lot from the audience, and is directly addressing a crisis that not everyone feels or realizes. The closest I can get to describing who would like it: if you've struggled or thought deeply about meaning and nihilism, and are happy to suspend disbelief to go on a journey exploring these ideas, please go and watch it.
