Y’know that infamous quote about Rick & Morty that doesn’t understand how enjoying things made by smart people is different from being smart yourself?
You have to be smart to appreciate this movie.
For better and for worse.
You can definitely enjoy it, taking it at its word that everything makes sense. It has some fantastic ideas casually sprinkled in, to make you worry and wonder, but not as part of any larger puzzle. The major thread of the film, and its conclusion, still work if you’re only kinda following it.
But when you trace what’s going on, you will find that the filmmakers did all their homework, and everything does make sense, even if it takes you ages to work out how.
