O Lendário Cão Guerreiro

... to the point of stupidity. Really.

No, it is not a "ripoff of kung fu panda." China and Japan are actually different places with different cultures.

This was also not someone "ripping off" Mel Brooks. He directed it! He's in it! And the role he plays is the same one he plays in Blazing Saddles.

Because it IS Blazing Saddles. The writers of the original are even credited. Given how many American Westerns were redone Samurai movies, it's a pretty established pattern.

It's definitely got some tongue-in-cheek references. It has some jokes that (as Mel Brooks movies do) push the line. But it tells a good story and has solid voice acting, so I'm not sure where some of the complaints are coming from.
