This was wonderfully weird and eccentric. If this was ever adapted into a US series, I think David Lynch would be perfect for this. That's the kind of strange this was. I can't fully explain what these Jellies were, what was happening and who the characters truly are and yet I was enthralled. Perhaps some of the episodes were better than others but this was a well rounded series overall. Each episode showed up some new interesting character and side-story with the one connective tissue being Nurse Ahn Eun Young. Jung Yu Mi was excellent as this school nurse who sees ghosts and other creatures. Her eerie smile and quirky style was instantly endearing was allowed for a living embodiment of what the show is about. Her and Nam Joo Hyuk, who plays the straight forward Hong In Pyo, were great leads to take us through the six episodes. The side characters and little plots were fun as well. I can't speak more love for this show. Watch it.
