This absolutely should not hit as hard as it does. It is a stick figure, some scratchy line drawings and a voiceover, and yet somewhere along the line It’s Such a Beautiful Day stops being a clever little oddity and turns into something weirdly huge.
Bill drifts through illness, memory, routine and whatever is left when your mind stops behaving itself, and Don Hertzfeldt somehow makes all of that funny, sad and faintly terrifying at once. The rough animation is part of the trick. It strips everything back so completely that the deadpan narration and the tiny shifts in feeling land even harder. Some of the jokes are so perfectly timed they would make much bigger films look a bit daft.
What really got me is how casually it deals with mortality. Not with swollen importance or Oscar-bait solemnity, but with this odd mix of silliness, tenderness and cosmic panic. It is bleak, yes, but also oddly life-affirming in a way that sneaks up on you. A strange little marvel.
