^"In ESB he is, in ROTJ he almost prefigures the emo butt-monkey we saw in the PT."
LoL, true....to me he seems mostly like the Emperor's lackey in ROTJ, up until the end of course. it's like all that fire that was in him from ESB when he was talking about overthrowing Palpatine just went down the drain.
Unfortunately I think that wasn't so much a logical character development as it was born out of ROTJ becoming the final movie and GL needing to quickly tie everything up.
Anyway, the movies hold up for me despite the issues. It just makes them interesting in a weird way. Still, any effort being made to have ANH Vader be much more like his ESB version is appreciated.
