Um... wasn't the show addressed to little kids? The best I can see is Japanese kids dirtying the studios with paint or toilet paper. XD
But there is always something OOC, it's natural. Some characters are better in one environment than the other. That's why Disney's games usually suck and Mario isn't that good in movies and cartoons.
Mario's problem is different though. Mario doesn't have much of a personality in the games so for movies and tv shows, they have to come up with their own. It's not that they get Mario's character wrong. It's that he has no character.
