I cant say anything for the show but I read the book (Which people tell me is almost a script of the show) and I think you should check it out.
I am NOT a star wars fan at all. I have seen the movies, once, very very long ago and would not consider myself a fan. The only other movie I ever remember seeing Carrie Fisher in was "When Harry met Sally".
The only thing I felt in the book you really needed to know (and I use needed jokingly) was that Carrie Fisher in star wars had "That stupid F***ing hair style".
I was never confused about anything and Star Wars did not overwhelm the book. It was more about her life through triumph and tragedy, and diffrent yet very random events that happend in her life.
I would deffinetly check it out.
