I dunno, I for one enjoyed his transformation from the Big Red Machine into the Corporate Kane. He had been doing the whole "masked monster" stuff for exactly 16 years, so he was stale as shit and needed a change. Of course, this current role is gonna get stale even quicker (in fact, it's already started to) but it's still a fresher take on the Kane character than continuing to be the Big Red Monster would have been.
Of course, it's obvious where all of this is going - he'll be talked down to by HHH and Stephanie and treated as their stooge more so than he already is, at which point he'll get fed up and eventually shed the suit and tie and probably choke slam everybody (Orton, HHH, etc.) And this change back to the old Kane will likely be accompanied by no heat. If there's at least some sort of respectful moment between he and Bryan at the end of it (as a callback to their friendship/partnership from before), then that'll at least be something.
