Dude Arnold made "kindergarden cop" and another movie where he was pregnant. And he did the right marketing moves because that made him a family movie star and his appeal was not just for hardcore male movies but for movies with a larger appeal, larger audience that turned him into a bigger star.
If you think about it Arnie became a bigger star than Stallone (even when Stallone had 2 huge iconic roles) and I think it is because Arnie since the beggining focused on not just making action movies but comedies that would bring him to larger audiences
Clearly the rock is modeling his career after Arnies and is making similar moves, which again are smart moves. You just dont see it because you are thinking subjectively and want to just see "GGRRRR action movies" but the rock is making smart moves to appeal to wider audiences.... and yeah definitely the torch is being passed
