Daria

While this episode may not be one of the best of the series (or even the season) it is one of my personal favorites simply because of the clever dialogue. I think the reason that many people do not like this episode too much is simply because of the subject of the episode being about the existence of guardian angels. Personal feelings aside, it is a great episode for character development. We discover that Quinn's character is not as simple as it seems--she does have a spiritual side and believes in guardian angels. Daria, for as skeptical as she is, even comforts Quinn at the end of the episode despite her personal feelings about the subject and Quinn herself. In fact, most of the cast debates the existence of guardian angels for the entire episode (many coming to interesting, if not uninformed, conclusions) while keeping the episode very light-hearted.
