Better than the novel? (possible spoilers)
I enjoyed this film, and think it might even be better than the book (personal opinion!). It was certainly less ambiguous than the novel, perhaps because it was shown from the point of view of Di, because it showed Miss G in situations the girls could not have seen.
It certainly deviated from the novel - I got the impression from the book that Miss G was actually quite butch in appearance, and Eva green is a strong lady but definitely feminine; and there was no scene in the novel that showed her going to pieces in public. Er, and it was set in England in the 1930s!
Nevertheless, the film picked up suspicions in the novel and made them explicit (Miss G being a former pupil etc) that I thought really worked in the film.
What do you think?
