My wife and I started watching this because there was a lull in available episodes of the shows we usually watch so we finally checked it out because we had heard so much about it.

For about the first 6 episodes it seemed well-produced and well written show but still seemed to be a kid's show. Then as it went on nuances in the characters and the plot became more apparent, and the lore and world-building took on more depth. By the end of the first season there was no longer any caveat about it being a kid's show. It was just a good show that improved almost noticeably every episode.

It's definitely one of the more interesting shows I've seen. Check it out. Don't let it's age or origins as a kid's show stop you. It more than rewards the time you spend with it.
