Before rewatching, here’s what I remember of Up:
1. All the tears.
Revisiting, that seems about accurate. The story of Carl and Ellie is beautifully rendered, which is why it stands out in my memories.
The rest of the plot feels incidental. The baddie's motivations don't make much sense, which is perhaps why I forgot about that whole thread. Still a fun watch, and worth revisiting every decade or so to see how I feel as I grow older.
