Depends on whether they're trying to make a series for adults or not. Game of Thrones and many other shows have shown people not only tolerate but enjoy shocking and violent storytelling. One of the heroes in the movie Kingsman is involved in a church massacre where everybody dies a VERY violent death (AMAZINGLY edited/shot scene). But there's a reason why, just like there's a reason why the townspeople of Tull turn on Roland.I think this guy is very right about why the first book at least would never be filmed literally:
You can see Hollywood executives coming to the part in Tull and going: 'Wait, the hero kills EVERYONE in town? The HERO...?'
I doubt even in a tv-series they would do that.
Roland is sort of an "anti-hero", I'm sure these are the same sort of producers that would say "Roland lets Jake die? We can't let THAT happen!" The Tull scene would have been one of the most memorable parts of the movie if they did the first book as a fairly direct adaptation. The final shot at the end of the scene when the smoke clears and Tull is nothing but Roland and a bunch of corpses would have been unforgettable. The people in Tull were possessed by the MiB. THAT would have been a heck of a lot creepier than him simply saying "stop breathing." They could have had the last living Tull person speak in the MiB's voice, letting viewers know who is behind the madness, right before Roland puts a bullet in him.
Heck, don't the Breaker kids die at the end of the new Dark Tower movie, without so much as a mention?
If a producer is working on The Dark Tower with the intent of sugarcoating the story for young teens, they shouldn't be adapting the material in the first place.
