This is a good point.
Modern movies try to appeal to everyone. Can't be too edgy or too opinionated, don't want to sick rabid hordes of haters on themselves.
And there's a huge segment of the Western population teetering on the edge of death or living in misery in various ways who are a literal matchbox waiting for a spark, no megaconglomerate film company wants to be responsible for setting them off, to the point where it's safer to sell mediocre and milquetoast movies rather than push an opinionated one and risk blowback.
Look at the Beetlejuice Beetlejuice or the Craft 2. Both movies built on a previous proven winner, both original movies had something to say.
Beetlejuice was not only a quirky romp through the afterlife but also a story about aboriginalism vs colonialism and whether it is right for the aboriginals to do horrible things to protect what is theirs, and also a story about how embracing change can help cross generational divides and how accepting people who are different from you can enrich your life.
It was very opinionated and had a lot of great subcontext. Same with the Craft.
The Craft was, on its cover, a story about what teenage girls would do if they got magical powers, which then turned into a series of biopics of the deep emotional damages caused by indifferent and hateful people. The movie dealt with racism, sexual assault, murder, mental illness, self esteem, and self acceptance all in the context of a teenybop horror movie.
Then you look at their sequels.
Beetlejuice Beetlejuice introduced 3 antagonists, Beetlejuice's wife, the boy, and Lydia's boyfriend.
It started three potential plotlines, the soul sucker, the life swapper, and the gold digger, and brought Beetlejuice in to deal with all three of them.
And then, 80% of the way through the movie, it threw all three of the antagonists and plot lines away and then rehashed the climax of the original movie with a slightly different set of clothes on.
What deeper meaning did Beetlejuice Beetlejuice have? None. No one had any value or made any sense. No one in the entire plot was irreplaceable. No one learned any lessons or grew in any measurable way. Nothing actually happened. They all woke up like they had a bad dream after Lydia's father's funeral, the mother died, the gold digger died, and then the story was over. If the movie had not happened nothing would be different for the characters except that maybe the gold digger would have dug more gold or something.
Then, the Craft 2. It's not a horror movie. It's a teenybop movie where girls get magic and do things with it. They have a trans person in it but she doesn't use her magic to address her transness in any way. There's only a tiny drop of racism, and no one has any real deep issues to resolve.
So, instead, they get David Duchovny in to play as some guy who embodies toxic masculinity, but who is also ineffective and purposeless all the way to the very end of the movie, when all of a sudden he goes murder rapey and then gets easily beaten by the power of feminism and witchcraft.
No one learned anything except GIRL POWER. Nothing really changed for anyone. There were no edges in the movie to explore. It was pointless.
Either sequel could have been much more poignant by touching on real issues that people experience. The Craft 2 could have touched on social media and the need to look like you have a perfect life. They could have touched on what a trans woman would do if she could remold her body with magic permanently or semi permanently like the girl did in the first movie. They could have made Nancy a bigger part of the movie and have her deal with David Duchovny instead of it being a girl power movie, and then Nancy could have taught the girls the things she knows being a former vessel of Manon with 25 years to learn and grow from the experience. It could have gone into a demonstration and discussion on how young women have so much to learn from women even 20 years their senior, and how working together and tearing down walls both of age differences but also gender differences can make the world a better place.
Beetlejuice Beetlejuice could have made a really fun story out of any of the three protagonists and plot lines if it had picked and chose one of them to run with and made the others the sub plots. The gold digger plotline could have been about accepting what is different about you and not allowing others to convince you to mask your weirdness. The life swapper plot could have been about learning how to accept that you're a normal person who grew up in a weird household, and how that doesn't make you weird and that it is possible to make both sides work together as long as each side values the other. The soul sucker plotline could have been played for laughs as at the end we could have seen Beetlejuice about to win Lydia only to be thwarted by his actual wife and dragged off into the underworld by the leg by her (and end up happy in the end, maybe seeing him slowly reinflate after she sucked the soul out of him, he he sex joke). All of those options were thrown out of the window and instead we get a meandering pointless movie that would have been fine if it had never existed.
Good movies have an opinion and something to say. Napoleon Dynamite is a perfect example of this. It's a bad movie in every measurable way. It's boring. It's slowly paced. It has no plot. It's like a 2 hour slice of life Jello movie. But then, the point of the movie gets driven in, that everyone has value.
It's a simple message told in a long and occasionally humorous manner, but because they didn't try to piledrive the message into you when it hits it hits hard.
Bad movies ramble even more than I do and never make a point for fear of popping a bubble. And media franchises know this and choose to make them anyway rather than be at risk of any blowback. After all, most movies released by a large franchise are profitable by default. The number of AAA movies that did not make their cost of production back in the last 10 years is vanishingly small, to the point where movies that only make 150% of their production costs are considered box office bombs and franchise killers. (Like the Golden Compass, that made $370+ million and won academy awards on a $180m production cost and was considered enough of a failure to end the entire series)
They know how to make good movies. They know how to tell satisfying stories that keep people wanting more. They know how to make a lot of money doing it.
So why do they keep not doing it?
I believe it's 2 things.
1: Fear of offending people and having massive blowback because of it.
The outrages over stupid things like the Little Mermaid being black is a good example of this. Who cares what color her skin is? She's a fish. If the story is good and told well then what does it matter?
But I get it, you can't convince someone who wants to be upset and outraged as a distraction for their own personal problems to focus on their personal problems instead of screaming about DEI or whatever 4 letter flavor of the day they have to rage about. This much is understandable. But still, that's no excuse for making a bad movie, they could have far more easily found the rage points and dealt with them and left the rest of a good movie alone.
But that brings me to my second point.
2: It's on purpose.
I've been thinking about this for a while, but I'm starting to believe that megaconglomerate media companies are intentionally making unsatisfying movies that are highly titillating for the same reason that Doritos flavors their chips in just such a way that you never get satisfied of eating them, that final burst of zest and flavor that would put you over the edge always just out of reach.
It's like the torture of Tantalus, satisfaction always being just outside of arms reach, but knowing that it's close, and occasionally actually satisfying the itch (like any good skinner box) keeps us diving in, spending money, buying merch, showing our love and support for the franchises that once scratched the itch for us in hopes that it will scratch it again next time.
They're doing it on purpose because they know that if you didn't get what you wanted out of this movie, you'll go watch another, or a TV show, or read a book, or play a game, something, because you came to get satisfaction. And if they blue ball you just right, you'll keep spending money until you can't afford to spend any more in hopes that you'll finally get what you're looking for.
I think it's on purpose and I think it will keep getting worse until it cannot get any worse, and then it will be replaced with something else that will be massively satisfying for a while at least.
