While its best years are past, there are still occasional brilliant episodes.
Some of the experimental ones are great. There was a recent D&D / fantasy hommage, and some good science fictional stories. They used to save these stories for the Halloween episodes, but not they just break continuity and run them through the year.
Some of the ordinary stories stand out. There was one involving Lisa and another offbeat girl creating a fantasy world called Equalia together. It ends with Lisa leaving things behind, realizing the real world needed her.
