Unique and consistent art direction, every visual motif was well thought out and implemented. The characters' archetypes may seem plain and overused in <insert present year>, but they seemed wacky and fun enough when I first saw it. Has just enough characters that a monkey-brain viewer can tell between them without knowing their names.

No storyline, every episode is self-contained, you can turn your brain off and simply click play. The one slice of life show that makes me think, "Take notes, Kyoani."

Wish they made another season.
