This show surprised me. It's more than just a teen drama. I appreciate the racially mixed casting and the delving into issues faced by biracial kids. All of the comparisons to Gilmore Girls are purely superficial and take away from the darkness that I felt this show did very well. I think the casting was really well done. I say kudos to the casting of the "teen" actors. They all looked pretty young (they looked 20 instead of 25-30 like usual in these shows).
If you are expecting something as light and fluffy as the GG, you will be disappointed. But if you want something entertaining with very dark tones and some pretty realistic teen characters... give it a try.
