Why doesn't Hollywood get that people don't care about...

Failure or not, if it made money or had success, it's going to be attempted again.  

It's a tried, tested and true story. It's played out in its own form but it can be used in other ways. Even in Aquaman, he sets out to find this ancient trident only the true king of Atlantis can hold. So of course Aquaman can pick it up because Arthur.

The only way to truly stop Hollywood from making more movies of a franchise that keeps flopping or is tired is for the latest film to literally gross no money at all.

Car chase scenes. 


Sure, the mechanics and car nuts and crack heads whack off to them, and claim they replaced the horse chase. WRONG! 


Cars are everywhere, and no one wants to see all these cars and city streets. They make terrible cinema as a rule. They denote a status quo, and just don't work in action

Also, the "lovable outlaw", the killer we're supposed to care about, the thief, the spoiled people who have all the resources and just act superior. Hollywood is in the mob family, has been for over 50 years, and so they glorify the mob and the criminals, and sane people don't care. They make a killing off the dorks who would buy anything Hollywood sells, but they'd do better if they stopped alienating law abiding, God fearing people.

I did, but if you want to keep it just at the characters and not at the influences, which I think are valid, then sure. They've been done. Glad we cleared that up and didn't move the convo anywhere else.

I've read Le Morte D'Arthur (though it's been awhile) and there are plenty of stories that could make for great films. I would enjoy seeing a film about Palamedes and Tristan for example.

I think the big problem is that Arthurian legend is often adapted into film as just being about Arthur, Merlin, Lancelot, Excalibur, maybe Mordred, and that's about it. I'd rather see them branch out with the less well-known stories from Arthurian legend.

Of course, that's just me, and I think they'd certainly bomb too. Nonetheless, at least they'd be more interesting. I do agree it's a stale concept and Hollywood is not going to make King Arthur a "cool" mega blockbuster.

It's the execution.
They are not trying to do an audience-friendly version of the story, but one that satisfies the political tastes of the ones funding it so it ends up sucking.
The Robin Hood films demonstrate this well.
The Russell Crowe version was morbid and slow. The 1938 version is still watchable.
