I really like the Castiel character, but Dean's feelings are so complex and the character is very developed. I know than the show is on the two brothers, but to me, Dean seems like the real principal character. Things happen to Sam, but the show is on Dean's reactions too.
And Jensen Ackles is such a great actor! He made it so natural! Sometimes I wonder if he is really like that in real life! ;P
