Simply Put, Jim is An Amazing Actor!
I loved him ever since I saw Across the Universe and then Boleyn Girl and 21, but he has completely won me over in One Day. Jim is such a natural actor and is always able to put meaning into every scene he does.
I have not yet read the book but really got a sense of a multi-dimensional character that Jim brought to Dexter. He went from a young, charismatic, good-looking guy to a charming but immature ladies' man; to an egotistical and selfish jerk; to a somewhat broken father and divorcee; to a man in love and finally to a mature and reflective adult. Phew.
Really talented, really gorgeous actor with a great personality to boot. Love everything about him.
