The Red Prince is a very well developed character that has got progression and(when comparing to other things in the game) well crafted and varied quest. All character should be like him in this regard. I think Larian have done a good job with him and should have done the same good job with a lot of other writing/story related...well, issues in the game. Conceptually the ending of his quest is brilliant, but is presented abysmally, which is a rather embarrassing let-down, to be frank.
Personally, I am also fond of him for his roleplaying part, and enjoy his company. I really started liking him after his private confession at Amadia's shrine in act 1. Wish that the origin characters in the game had more to say about what is going on around.
