I'm not sure if ridiculed is the right word for it, but celebrities and gimmicks seems to be his default go to ideas.
Price = Celebrity guest spots + too many themed shows to mention.
Millionaire = Celebrity contestants
Primetime Wheel = Celebrity contestants
J! = Likely will have Celebrity contestants or themed shows with a new host
Seeing a pattern yet?
Not really.
Millionaire and
J! have done celebrity episodes for years. Theme weeks aren't new to
J!, with Kids Week, and various tournaments. The Battle of the Decades could be seen as a gimmick, but instead uniquely incorporated its past. I think Mike realizes the difference between that and the decades episodes
TPiR did a few years ago. I also think he realizes the two shows are completely different animals, so you won't see something like a daytime soap star doing Final Jeopardy! A cameo during a main game video clue? Maybe.
Wheel has done theme weeks for years, and while I think the show needs a shot in the arm, I don't see this being any worse than what Harry and Co. have tried for the last two decades.
I think this boils down to you just don't like Mike or anything the current crew does on
TPiR. Mileage may vary, etc.
