This happened to me just this past week. My wife and I finished season 7 of Natsume’s Book of Friends and the final two episodes are so dramatically different from each other. They are both excellent, probably some of my favorite episodes from the whole series. One is a heartbreaking tragedy and the other is very touching and optimistic. It’s an anthology show, so it’s not crazy for this to happen, but it’s just the first thing that popped into my head seeing this question.
