You've got it all right. I agree with you 100% on everything that you said about the movie as well as the cartoons.
My favorite thing about Bakshi's work was the voice of Aragorn, played by (the british) John Hurt. His growling low voice was so wonderful, plus- his accent is genuine! I am a fan of Sir Robert Stephens, who did the voice of Aragorn in the BBC radio plays. Once again, it is his low, warbling, noble-sounding voice and accent that made the character one of my favorites. At least in the Bakshi version, Aragorn's lines are not changed so significantly as to detract from the character's good and noble heart.
One can see that Bakshi's Aragorn might even have been modeled on Sir Stephen's face - perhaps he was whom Bakshi wanted originally. But that's okay.
You know, I wasn't phased by the shortness of Aragorn's tunic, either. I did, however, wonder how he kept the bugs from sneaking up his crotch!
I do believe that Jackson's films would not be nearly so good without Bakshi's contribution to the visualization of Middle Earth. Thank goodness for his work, else I probably would not have liked the film one bit. In this, Bakshi won....even though his animated film was a bit of a dud. Thanks, Bakshi!
