You know, there's a ton of anime that's just as limited in its animation as TAS was. I see plenty of TV anime that features long shots where nothing moves except a character's lips, or the camera panning slowly across a static scene. Plenty of anime shows are built around the reuse of stock sequences, such as henshin/transformation scenes or standardized attacks. This is true even of some of the classier anime like Ghost in the Shell: Stand Alone Complex, where some of the action animation is really rich and dynamic but there are plenty of long dialogue scenes with virtually no animation at all. It puzzles me that anime, even from the '90s and '00s and beyond, gets a pass from fandom for its limited animation, but Filmation's '70s work gets trashed for doing the exact same things.
Good point; anime is often stiff, recycles run or fight sequences, yet its fans write that off as "style" rather than the limitations of the animation.
