Hmm, I think I'll stick to enjoying the TV version with its lovely, atmospheric camerawork and subtle characterisation. The writing was full of staccato sentences, often telling rather than showing without any kind of subtlety. By the end, I was left baffled by the preposterous storyline. We are left without an adequate explanation, I felt, for some of the most important features of the earlier plot.
Yet another interesting example of how an indifferent book can be transformed into great television drama.
