I loved it too and was (am) completely captivated by Douglas Booth - stunningly beautiful, but beautifully expressive too: not just a pretty face.
GA as Miss Havisham was inspired - tiny and mad. It was the veil that flew off, not her hair - fantastic scene. It looked like an accident to me in that she was too out of it to realise how close the flames were to her dress.
imo older Estella is a luminous beauty... if she were not so thin! the thinness aged her and stamped out her beauty. What on earth did they do to her hair at the end - she looked like an old maid. I think they got the casting right - right mixture of beauty, disdain, cruelty - but there was confusion throughout about how exactly to portray her and I think she lost out because of it.
Young Pip: lovely (watch this space); Joe utterly fanciable (I do so like a kind man) but I was so disappointed that they didn't include him throwing his boot after Pip as he drove off in the carriage to his GE. Poirot as Jaggers was slightly off-putting, not least because Poirot's mincing step was sometimes apparent - Jaggers would surely have strode, tails a-flapping. Molly looked like Pip's mother (same lips) not Estella's. Liked Magwitch's fabulous tattoos but would have liked the twirling at the beginning as per the book.
Enjoyed it immensely but entirely eclipsed in my affections by the gorgeous Douglas Booth - too, too beautiful for words.
