While the show has many sub themes, the primary story of the show is the relationship between a teenage boy and his family. The boy, Kenny (Noah Galvin) is gay and the show is mostly told through his point of view. But this is not a show made for a niche audience, it is a show made for all viewers.
My only criticism of the show is they seem to mock Christians, Catholics in particular, for no reason. For instance, they have a stature of the virgin Mary on the toilet tank. Jesus shows up in a few episodes, and has a few lines that do not really add to the plot. Hopefully there will be less of this as the show matures.
The show has a solid cast. Noah Galvin in particular does a great job of making the gay teenager relatable, serious and funny. All the cast is quite good.
