Wow, I reviewed this when it was still in its development stages as a possible Amazon original, and gave it a thumbs up for being a very visually rich production, and, at the time, seemed to have a kind of education for kids about the natural world. Maybe I'm not remembering the old pilot correctly, but I thought there was some science and math involved in a very bare bones kind of way. There is some science here on an emotional level in regards to what scares people, and how some scary things aren't scary.
Another plus is the scripting. The director used some time old sight gags blended in with the story that made me laugh out loud. Stuff that hadn't seen the light of day since the Three Stooges or Laurel and Hardy, and still holds up.
If you marry this to an incredibly rich visual background and stop motion characters who are also very well designed, then you got a very dazzling production on a number of levels.
You know, I could prod this, poke that, and say add X, Y and Z to improve the thing, but it's not my show, and as a middle aged adult, I laughed and enjoyed the old time gags put into a show meant for children.
Take that for what it's worth.
