For those who practice an Okinawan style of karate, what do you think of japanese styles of karate ?

I have a pretty bad opinion about japanese style karate even though I come from a Kyokushin background. My main criticism would be that basically they built a new martial art with new customs without really understanding the original martial art.

But this is just my opinion !

I wanted to know how people who practice a more "authentic" Okinawan style of karate think of this modern karate ?
