Why was it necessary to tell the story through the ghosts of her mother & father? Was it just pretentiousness on the part of the writer or was it to save the trouble, or time, in acting out the relevant events?
If it was to save time, why could they not give it a longer time span? They barely touched on the latter part of her career. Cilla got 3 episodes (admittedly on ITV) and was all the better for it.
