The show isn't quite "Gilmore Girls" plus dancing, but it's pretty close, and that is not a bad thing at all. "Bunheads" comes from "Gilmore Girls" creator Amy Sherman-Palladino, and you'll find a lot of familiar elements here.
It is very seldom when watching a TV show that you find yourself completely clicking with it. For me it's happened a handful of times over the last 10 years or so. One such time was when I watched House.
