Short version:
I LOOOOOVE this show!
Long Version:
Sure, Kid Muscle (Mantaro) is a loser, a young man afraid of even his own shadow, and he has flatulent super powers...but that's what this show is about. Goofball moronic entertainment. See...the 20 some odd year history of the Kinnikuman is a rich <snicker> and storied <guffaw> one full of the one thing guaranteed to get kids of ANY ethnic background to laugh: Disgusting, over the top, POTTY humor!
I was a HUGE fan of the toys when they were released in the US back in the mid 80's, the little pink MUSCLE figures that you could buy in a trash can. I loved everything about them. And I love them even more NOW that there's a show to go along with the toys of yore I so loved to collect.
In short, if you're looking for a serious anime, then ANYTHING on the Fox Box is not up your alley, however, if you're willing to let yourself be taken over by the kid inside, and for just a second, not be a grown up, you'll find yourself laughing into your Frosted Flakes 9:30 am, every saturday.
I give this cartoon 4 1/2 out of 5 stars.
