The interesting thing about "Ratking" is it keeps almost ending. I can't count how many times there was a grand finale, a climax, and it felt like the end of the show. Then it continued and had another grand finale. Eventually it did end.
Like I said, my favorite episode. I'm still not taken with "Zen". I've seen superior shows, but it's okay. It ended at a good point, leaving it open for next season.
My grade: B+
