I didn't think I'd like this just based on the premise, but the more I watch the more I want to keep watching. It's interesting, fun to watch and weird and I'm kinda invested in seeing the mystery unravel. The summary makes it sound way more whimsical than it actually is.
Oh and the animation is excellent, but it's those guys.
