I don't get what you are complaining about. The similarities between Hiss and Kaa and Lil John and Baloo, and the fact that like twice in the movie, their motions are the same?
They are different characters, and there are only so many ways to draw a snake. Hiss's actual movement is nothing like Kaa's. Yes, they drew over some old frames from older movies, but they also created lots of new motion.
The voice acting was bizzare how?
I think the songs and music in Robin Hood are better than just about any of the modern Disney movies.
It's actually worse than I remember.
Disney was the pinnacle for classical animation. Working on Robin Hood was an insult to the men and women who over the prior 40 years brought the studio to those heights and frankly demeaning. (Similar to the way that Disney insisted that Tytla rotoscope the sorcerer in Fantasia.) It was a film made by bean counters, not animation artists.
Other than Ustinov the voice work is nowhere near the pinnacle that The Jungle Book was.
There are only so many ways to draw a snake? Wish I knew that when I was teaching animation, I could have saved my students a semester.
I'm glad you like it, but to call it the "best animated film" is an insult to "best" "animated" and "film."
