Pride and Prejudice-Darcy's change

One of the things that I found a bit troublesome about the original Pride and Prejudice was how Mr. Darcy's character didn't seem to change all that much for me.  We do get to see how he changed in that he acted kinder towards people after Lizzies rejection of him, but after watching the television adaptation, I got to see how he changed emotionally as well.  To me, it seemed that his character in the book remained roughly the same from the beginning to the end, as a sort of proud, intellectual man, so I was really happy to see how the adaptation was able to play off more of his emotional state during his transformation.
The first scene that illustrates that's change in the greatest was when Mr. Darcy first proposed to Elizabeth.  Up till then, Mr. Darcy always had this emotionless, almost irritate look to his face and acted in an extremely intellectual manner, never allowing his emotions to show.  This image of Mr. Darcy is immediately shattered in this scene when he enters Lizzies room, practically running, with a look of unease to his face.  He then proceeds to take nearly a full minute pacing back and forth in her room, nervously staring at Lizzie while making vain, hesitant indications that he wishes to speak.  These actions destroy the image that was earlier built of him in the series, with him often standing still with his own thoughts, and it was certainly a change to what I had built of his character from reading the book.
In all, I liked how the television series made Mr. Darcy appear more human as he changed throughout the story.  He never gets fully over his intellectualism, and I'm grateful for that, as it is still a major part of his character.  These subtle changes to his character made me feel happier for both Mr. Darcy and Elizabeth, as now we can see how the both of them change for the better, all for the love of the other.
