I watched the LotR cartoon just out of curiosity and thought it to be terrible but entertaining (and this from a chick who has "Plan 9 from Outer Space", dubbed the worst movie ever made, on DVD, so perhaps my opinion is not valid
)
But yes, Pantless Aragorn, Viking Boromir, and "Aruman" were all just too much to handle. BTW, they called him "Aruman" because Bakshi thought Sauron and Saruman sounded too much alike and it would confuse people.
