Donnie Darko
Initially while watching the film, I was genuinely thinking what the absolute fuck is going on. But this is one the movies, that you only get in the last 15 mins of.
There are multiple renditions of it to perspectivize from, like the time travel trope, the child of God trope, final destiny trope that one can have.
The movie left me pndering on the actual question of whether his sacrifice was worthy?
