Moving, but maybe still depressing?
So warning of spoilers, but Arthurs sole mission is to find the place he is supposed to visit, before he can finally die. (His only wish because his girlfriend vanished from existence)
And in the end he finds the place, which is not what anyone expected and they indeed all die, including his daughter.
After they concluded, there is no other place, no other home, because, every other place is also falling apart. Pretty dark ending in my opinion.
