I am a real nit~picker when it comes to Jane Austen.
I think it is always a mistake to try and compare any book with a TV ot film production,they will never meet the images we have in our heads.
Having said which,I am (so far) quite pleased with the new "Emma".
Only two small points.I think the actress playing Emma is a trifle too modern in her way of moving and talikng,but that's fault of the director not the actress.
I couldn't fault the dialogue (which is where many filmed versions fail) except for one character who used the expression "up front" when referring to a monetary payment.I can't think that this was a period expression.
Unless someone can disillusion me (please).
