If you actually take a step back you'll notice that there has not been a new crazy superstar in Hollywood of any race or gender in quite a while. I mean you still have the names that you've always heard like Leo, Brad Pitt, and you have a handful of other young actors and actresses that have come kind of close to being a thing but then they only end up being a thing for maybe a year or so. Everyone else that comes to mind has been an established name for a while.
I can't think of a single actor or actress under the age of 30 that has been popular or at the top end of the highest paid or most "in demand" longer than maybe just a few years outside of the MCU.
Not sure what that says about Hollywood or the quality of the latest batch of the actors but it is kind of weird to me that after having consecutive decades of having some kind of star or Stars rising to the top and then staying there is weird to feel like we haven't really had one here recently.
