Harry Potter created a genre; schools that taught very unusual things, but had school structure, nonetheless. There are a large number of series that have used this idea, not quite a plague of them, but too many. Most of these are watchable, but they aren't very good. This is a huge exception. Think of "Pulp Fiction" before you decide to skip this. Like Pulp Fiction, this series adds a touch of philosophy, honesty, and ordinariness into the plot theme. There are also occasional honest glimpses into every human reality. This is really a very good series.
