Han Solo in this movie is unmotivated, poorly acted, and completely inconsistent with anything ever this guy has done in the 2 previous movies.

I disagree with inconsistent. I say he's changed. They came back for him. I don't think Han Solo ever said "I owe you one" to anyone in his life before ROTJ. Han is now a team player, someone willing to volunteer to help the Rebellion and I think for the first time, he's someone deeply in love.

Hmm... I don't think I've heard/considered this interpretation before... I really like it. He's sort of out of his element. I think the "coming back and saving Luke & the Rebellion" was new for him at the end of ANH, and I think he felt torn by his old life style and his new one for most of ESB. He's about to go his own way again (maybe) when Hoth is attacked and he doesn't really get a chance to break free for the rest of the movie. His situation with Leia and his personal interaction with the Empire deepens after they leave Hoth... so I guess you could say he's decided to throw in with her and her cause by the end of ESB... but perhaps it's that they came back for him in RotJ that really changes him.

Good post, Boost!
