Rhoda is willing to better her life in a very selfish way. She doens't like to be a cashier any more and in the end she watches herself becoming a doctor.
That's a big step which wont usually be happing in reality, but it's possible.
Her feelings and thoughts are clearly shown, so that everybody can find oneself within again. There is no huge difficulty for her to change her life, besides the risks which always comes along. So it seems a bit to easy for her to fulfill her dream.
From the first second on, there are these nice British accent and attitudes which guides you through the episode.
So we'll have wait for the second episode to see if this series is getting better and shows more drama than this one.moreless
