I too had high hopes after the first episode. However, it drops off quickly after that. I agree that young Jane looks nothing like older Jane, which led to confusion on my part. Also, the daughter was absolutely infuriating in her random behavior and ability to magically figure out everything even though she can't even seem to take care of herself in real life.
What makes a great show is the ability of the writers and actors to draw you in and make you care about the characters. It totally missed the mark on this for me
I had to stop watching after episode 4, I am surprised I stayed with it that long.
