Odagiri is too busy being a family man to give a **** about them Karate Bugmen...and who can blame him? Still he was trying to be a serious actor I think and the roll of Kamen Rider is an easy way to get type cast, or so some actors may or may not fear. Doesn't mean he wasn't good at it, which is probably a sign of his skills as an actor.
But I regress...I don't know the guy or what goes through his head. For that matter I don't know what goes through the minds of the Japanese acting community. I just like guessing things and writing stuff that may or may not make sense. I'm fun that way.
