I certainly don't think Okada phones it in. As the face, he is the work horse, though that could be said of pretty much every Japanese promotion, regardless if gender. That's just the way the culture is.
I just feel fans are suffering from burn out. They latched onto Kenny because there was a possibility of change, they have backed LIJ because it's different and goes against what Chaos and Okada is. They don't along to Kaze Ni Nare and back a sociopath in Suzuki and his stable of young boy abusers.
Okada used to have some grime to him before the mega push to replace Tana, and truly I blame the fact they don't want their face to be a heel. Inevitably NJPW is gonna have to really change that with Naito or Kenny and honestly Kenny isn't even all that and anymore.
