Half-Earth perhaps, but I didn’t see much actual solarpunk. The only society we see seems to prefer automated and sterile mass agriculture as well as consumer capitalism (the protagonist is a product). I suppose the attempt to rebel against this given purpose could count as punk, but is it solarpunk? The story has very little to say about society.

Visually it was beautiful, but the pacing felt a bit too fast for my adult brain.

I liked the implied history from the underwater landmarks and human structures.

The three novels are quite good as well, targeted at kids, you can probably read them as fast as watching a movie.

I like this, will have to check out the novels for my kids too!
