Every teenager deals in his or her own sexuality and has to face it and figure out how it can coincide with the rest of their lives in a healthy manner. And try to navigate it in our modern society which is wrought with stigma and taboo and repression and sort of as a result these inner monsters that some teenagers really struggle with.
I think it's because it's so different and it takes risks. Plus it's really smart humor. It gives the audience credit in terms of not needing to tell them when to laugh. I love that about the show. There's no laugh track.
