"Suburgatory" is quirky. If you can't get past that statement, then you might not like the show.
But if you can, check it out, because "Suburgatory" is an excellent show featuring lots of talent.
The central theme--as you can tell from the title--is a critical view of suburbia. In the land where consumerism is the primary goal and people are themselves consumed by appearances there lives a high-schooler named Tessa (Jane Levy) who moved from New York to the land of weedless lawns and designer labels with her single father George (Jeremy Sisto). This is no "Who's The Boss". In "Suburgatory" Tessa and George are a complete family in themselves.
Although suburbia is a target of the humor, the show lovingly lampoons all aspects of society, including the central characters, who enter into some questionable relationships. They are far from perfect and the writers allow us to laugh at them and with them.
The rest of the cast is AMAZING. Three or four of them you will probably recognize, but they all rock. Comedy never had a larger cast of funny people.
As for the quirk factor, "The New Girl" wishes it could be "Suburgatory". It is quirky, but it may be too far out there, often substituting silly for insightful. "Glee" revels in the quirkiness of its characters and their actions, but it often feels like it is doing quirk just for its own sake. I only hope that "Suburgatory" keeps its edge. The best episodes have something to say and remind us of the things that are truly valuable, e.g. caring and self-realization.
