Thank you, Essex for pointing out that this topic has been covered in a recent thread.
I have merged the two to avoid too much duplication.
There is also an earlier thread comparing the cartoon with the Jackson films here:
Cartoon vs. Movie
I said my piece in the thread linked to above. But I will reiterate one point. The Bakshi cartoon was made over 20 years ago, when today's technical wizardry was simply not available. It may seem laughable now but it was all that we had back then. Certainly, when I saw it at the cinema aged 12 (when it was first released), I enjoyed it and I still have fond memories of it. Even if, looking back, I do find certain aspects of it strange and amusing now.
