I should preference this with I haven't consumed the book or the movie. I just watched a couple of videos about the movie. They of course race swapped a few characters. One race swapped character was a man named Peter. In the book he's white in the movie he's black. In the book ending a man named Raymond is the final walker and he continues walking, hallucinating a dark figure he is trying to overtake. In the movie Ray sacrifices himself so Peter can win.
Peter uses his wish from winning to ask for a weapon. He then shoots the major overseeing the walk and walks away. So the race swapped black guy wins and it can be implied began a revolution against the current facist regime. I think the messaging is pretty overt here.
This likely happened with Stephen King's approval. He's as deranged as any other lefty icon and just as eager to ruin his life's work to suit their trendy narratives. Welcome to Derry looks the same, so far all of the teasers and casting would have you think Derry was a black town that somehow turned white by the time the original movie comes around. It's desperate, sloppy, and dishonest.
