Really great to see Harvey back. This show has a genuine sweetness all over that's grounded and not saccharine. There are positive comparisons to Hey Arnold apparently, and that sort of thing really helps this show stick out on Nickelodeon's channel. Certainly more thought provoking and gentle than their awful abrasive live action programming. It's expected a cartoon about children "gets" children better than sitcoms starring children meandering around 1980's fam/com tropes done poorly.
I really liked the book episode. It had a nice gentle "books are fun" Aesop without getting preachy and hypocritical, and also finding a new angle about it too. It's confounding to a fan when their thing that they thought was special blows up. You have more people to talk about it, but suddenly, you feel less special because you found something that isn't mainstream that became mainstream. This was so much better than the stock "books are for nerds" or "television makes you stoopit" pro-reading messages in kids' shows. I'm happy that a show where one of the parents works at a library that's fairly important to the community manages to give that subtle, gentle, and respectful importance to reading.
