Sorry about the bump, but I just recently marathon'd the series. I don't really have much to add in regards of just how good the show is that hasn't already been said, but I do want to say that I absolutely love what the show is doing: making the supply to meet the demand of quality children's shows. The color choice for scenes, characterization, and plot each have me sold on the series so far and I'll probably end up waiting for new episodes as they get online.
Also, what I love probably even more is what the show's creator, Rebecca Sugar, is doing with
her YT channel. I think it's amazing that instead of DMCAing her fans, she's actively liking her fans' content on YT. It's rare to see stuff like that but I hope this becomes more common place in the future.
All in all though it seems like the show staff have fun making the series, the fans love it, and it's all just positive.
