but he is also on his own turf.

I realize this quote from a NY Times review is of a director's/actor's interpretation, but I think it is an interesting take on Darcy's character, relevant to his change of character.

"Mr. Firth might have been far more dashing, but Mr. Macfadyen's portrayal of the character as a shy, awkward suitor whose seeming arrogance camouflages insecurity and deep sensitivity is more realistic."

Any dynamic character in a novel must an impetus to change. Darcy's starts to change as a result of Lizzy's reaction to his proposal. It takes time and introspection, which we are not privy to since Austen chooses not enlighten us with two plot lines; instead we only have Elizabeth's heart to read.

Do you think the above is an accurate characterization of the literary Mr. Darcy?
