Everything Everywhere All At Once is a psychedelic movie about suffering and Buddhism.
It's deliberately overwhelming, and to good effect. The very first moments of the movie have the protagonist switching between Chinese and English, making it a strain to follow conversation with her even as she strains to hold her life together. She's becoming estranged from her daughter; her business is being audited by the IRS; her distant father is visiting; her long-suffering husband might even want a divorce. In less-deft hands, this litany of problems would be somewhat dull, but Daniels introduces them in pieces, at once, switching back and forth so you feel overwhelmed with the multitasking.
Later, of course, the movie switches to a multiverse. This is the first somewhat artsy movie I've seen that uses the multiverse as a hook, and it does it tremendously well, to the degree that you cannot help but look at Marvel's stuff and feel sad at how little it takes advantage of the concept.
Ultimately, the movie is a reflection on meaning, suffering, and what one should do in a universe that offers you no pre-packaged meanings. Highly recommend. The part before the rock part, with the overwhelming flashes of alternate Evelyns, and the Racacoonie plot line, were my favorite.
