Two things which don't surprise me about this cartoon show: that it was made in the first place and that it didn't last long.
Timing is a major factor. "The Karate Kid" movies were still fresh in the minds of the public at the time, otherwise the cartoon wouldn't have been green lit.
I can't take the episodes too seriously (folly to do otherwise), so it's simply a case of switching off the brain cells for the duration.
The animation itself, has the distinctive juvenile look about it. Children aged between 7 to 10 might find some appeal.
"The Karate Kid" has long faded into 1980s cartoon obscurity but I can tolerate the show in small doses.
