I watched the first 3 episodes last night.
I really liked the idea of them being random lives that shared the same birthday and just have common themes of life. I'm not sure that I like them being related(though I like how they pulled it off).
They have already added more twists than I care for and though I did like Parenthood, I don't want this to be just another version of that.
Having said that, I did enjoy it somewhat and will give it some time.
Btw, last season, I liked Code Black for about the first 6-7 episodes then they just kept having one unbelievable thing after another and finally it was just enough for me. They jumped the Shark in season one. LOL
