There are two elements here.
Reboots. Woke.
Reboots exist for multiple reasons. 1) It preserves an existing Intellectual Property (IP) that a company has. 2) if the company already has the IP under it's belt, licensing and distribution becomes far easier, and cheaper, allowing for it to do whatever it wants. 3) There is less risk associated with an existing successful IP, because the company can usually rely on a base fandom to come out. Less guess work means less risk. 4) As the international audience has radically expanded, it makes absolute commercial sense to rehash older IPs that worked well in existing American/European markets, and expand them to new markets (largely China.).
For many many, MANY years the above 4 points, especially the 4th point, worked out really well.
Woke.
This is a bit tricky and in my opinion comes down to 3 things. First, since the mid-20th century there has been a consistent well-to-do younger generation demographic that was has provided a revenue stream to entertainment media. This went into hyperdrive in the late x-gen and millennial generations, in the 1980s and 90s. Just think how much entertainment was specifically targeted towards kids born or living through those ages – consoles, cartoons turned toys, music.
Second, in the wake of that boom, that I think lasted well into the late 2000s and early 2010s, there was a new cohort of CEOs that relied heavily on the appealing to those "younger demographics" borrowing much of their thinking on their own experiences either growing up, entering the corporate ladder, or etc.
Third, the rise of HR, "Woke ideologies", and aging, out of touch CEOs. It is no secret that much of the entertainment and technological powerhouse exists in one of the most progressive/woke places in the country (California). These industries rely on a local workforce that is consequently very progressive, and many of the higher ups are extremely dependent on the information they are given by younger staff members to guide what ought to be green lit vs not. Couple this with social movements, such as the "#Metoo", trans-gender rights, LGBTQ representation, BLM, etc, no executive, no person in any position of power wants to be the target of any of these movements. They comply easily with what their underlings say.
And so you have a perfect storm of people who are completely disconnected from the mainstream audience, dependent on information from younger "with it" people to tell them what the mainstream audience wants, but unwilling or incapable of ever pushing back criticism when the metrics don't add up. At the same time you have China which is pouring billions into entertainment industry to the point where even poor reception in the US audience base doesn't sink a movie and lowers risk of a poorly performed movie. You have young progressives being in positions of indirect power, and use that power extremely effectively, and since there is no incentive to push back (risk of alienation, criticism, public scorn and outrage), and a little risk of failure (over-seas markets may – and do – make up the loss of revenue from a poorly received film in the US), there is no incentive to push back.
Ahhhh..
But this has started to change. Now that China has started using propaganda to make-or-break hollywood films, and now that China has turned off the faucet of easy money flowing into Hollywood to any company that doesn't comply, things start to become more interesting. Couple that with a whole pipeline of movies scheduled to be developed, made, invested in pre-COVID now having to be designed for and released on theaters that are effectively half empty, Hollywood is going to start feeling a TON of financial pain. And since "woke" media becomes an increasing financial burden it's going to make it far more easy to push back.
At the same time, there is an exodus of technological jobs and entertainment OUT of California meaning that these companies are going to start hiring people in more … diverse places – leading to a more diverse work place – which will ebb the power of the ideologues within.
I predict an increasing pushback from Hollywood on "woke" media in the coming months, and we are already seeing cracks (Marvel canceling New Warriors".)
