IMO, he should be taking as many serious roles he can get. Indie films, arthouse projects, supporting roles in dramas/thrillers where he can hone his acting chops. Robert Pattinson was a joke before with the sparkly vampire stuff. Then he did like 5-7 indie films that were good. Changed the perception of him. Bautista is another example. Do what they're doing completely. Then the Rock needs to work with a director to make a fire ass action series. What John Wick did for Keanu....The Rock needs something like that. Dark. Gritty. Serious. If the Rock can get his own John Wick type series, he'd be good
You add that with all the other serious film projects he'd have in his catalog by then and he'd be on the right track
He needs to avoid the mindless garbage he's been doing.
