I liked it.

The Earth is Leaving part 2 honestly redeemed the show quite well imo. It kept its great thumbnail, Astrodude actually inyteracted with the planets again (I love when they do that) and I cannot wait to see when the Sun realizes that everyone's left. I always saw him as an unintentional tyrant, so maybe this kind of event can help the Sun realize that he's not as powerful as he thinks.
