Man, that's so horrible. Especially when you compared it against the scrolling background episodes that the Fleischers did, and those from the 1930's!
The animation in the Star Trek animated series was only slightly better than that Popeye cartoon:

There's almost no movement!
One of the biggest problems with H-B cartoon from the late 50's to the late 70's though was how bad some of the writing was. Just laughably bad, especially on the lower-budget shows. And a lot of really awful attempts at humor. On the other hand, like MST3K, it's fun to see just how those shows back then were.
