The 1978 Ralph Bakshi animated version of "The Lord of the Rings" is a snooze-fest that ends up putting me to sleep almost every time.
The plotting is good for covering "The Fellowship of the Ring", but then it gets muddled as it delves into "The Two Towers" events. I got sooo confused with what was going on.
The rotoscoped animation offered realistic movement, but sketchy and inconsistent details. Sometimes the cels used backgrounds of colored lights to convey the magical effects in some scenes.
The Leonard Rosenman musical score was epic, dramatic and an up-beat military march.
It bothered the heck out of me they did not make another movie to finish the story! Instead, we got the cheapass made-for-TV "Return of the King" with its tacky songs and oafish animation.
