does hint at an actually valuable & mature idea (that faced with the hypothetical decision to have a different version of your life, you should always choose the one you have), but this movie is fundamentally unserious about the realities of the world

it also offers a nice summary of nicecore: ha ha nothing matters we're all just small and stupid specks of dust in big universe so just be kind and everything will be alright ha ha

which is the kind of juvenile worldview that I want nothing to do with
