Really a credible version of the story based on the novel by Gaston Leroux - which I have only read in abridged form. I'm pleased that in many ways this episode goes back to the novel rather than treading the path of the (sound) movies with their wronged composer, burned by acid.
The choice to end the story rather abruptly in a way much different from the novel was the price they paid for having character development and quite a lot of detail in the early portion. Certainly I don't miss the elaborate mechanical torture chambers of the novel. And, unlike the novel, the Phantom is not allowed to simply slink off and die.
Pretty good.
