I know Bakshi's version has A LOT of issues, but I grew up watching it again and again and I have very fond memories of it. I'm aware I am in the minority.

One of the scenes I love is Boromir's death (video link)... if you can ignore the "not-enough-budget" Uruk-hai. I like the roughness and lack of music once Boromir's is hit with the first arrow.
