It's not like she's a good actress, which is another thing that Hollywood is suffering from; the next generation of movie stars does not exist. Picard Season 3 is only as good as it is, and I use that term loosely, because its cast are built out of literal Boomers that understand acting as a craft. Bad Boys 4 literally is built on middle-aged actors that were big 30 years ago. Now we have literal whos as leads and they're more about repeating DEI messages than performing.
I don't agree with this. Maybe if your viewing habits only include genre TV shows, but the younger generation of movie actors is not lacking: Emma Stone, Paul Mescal, Timothee Chalamet, Aaron Taylor Johnson, Elle Fanning, Anya Taylor-Joy, Jacob Elordi, Florence Pugh, Austin Butler, Saoirse Ronan, Glen Powell, Sydney Sweeney, Barry Keoghan, Jodie Comer, Jesse Plemons. Pedro Pascal is probably also a legit star at this point, though he's older.
(If your response to that list is "I don't know who those people are" then I'm sorry you don't watch movies.)
You can argue that there isn't a generation-defining, lightning bolt talent like Will Smith or Jim Carrey in the current crop and you might be right, but those guys were outliers in their own generation as well. Time will tell. Leonardo DiCaprio didn't really come into his own as an actor until he was in his 30s, prior to that he was viewed as sort of a pretty-boy lightweight best known for Titanic.
We're not seeing a lot of quality people in streaming shows because it seems producers opt for lower tier actors to keep the budget down (and to keep the old guys happy, I'm sure Patrick Stewart was making more than the rest of the cast combined for Picard), and besides, no actor with a thriving movie career wants a TV production eating into their schedule when they're in demand.
