The show is a lot of fun for both 7 year olds and 40 year olds. There's little exposition before jumping into a lot of revelation from the future, but that's all setup for fun independent episodes.

The animation style is good and the voice acting is great. I'm not sure the agenda behind the hate. My guess, people don't like the warning about climate change. It's barely part of the story, so if your politics get in the way, just pretend there is another reason for her to complete her to do list. Some of these reviews are preposterous. It's one cartoon I actually look forward to watching with my kids.
