Far better animation than most modern day anime, which is supposed to be the pinnacle of animation. Crazy to see how much entertainment in general has regressed.

Rankin & Bass did Thundercats, and I'm pretty sure they're an American company. They also did the animated movies for The Hobbit and The Return of the King. And The Last Unicorn was another one I remember.

They're pretty cheap/crude, but that's what I grew up with lol. At least their work wasn't overly silly and cartoonish. I mean, their cartoons weren't overly absurd or whatever—the plot was usually serious.

I swear this song plays on the car radio two or three times when I travel around.
And now I can't get the lyrics out of my head. One of those 'sticks in your mind' songs.
