Odagiri has stated in interviews that he never hated Kuuga, just that he didn't want to act in toku productions anymore, was all.
He dipped his toe into things, found it wasn't for him, and moved on.

It's just that the internet is a giant game of telephone, and since most of these kinds of interviews aren't translated, we only have 2nd hand info to go off of. And they interpreted "I'm not interested in returning" as "I hated my time doing it"
