In order for the rest of the chapters to get adaptations, The Dark Tower needs to do well, so it needs to win over an audience.
In general, though, these TV spots repeat what has been said in the trailers, suggesting that there’s less to be learned about Mid-World and Roland’s quest in The Dark Tower than we might have hoped.
I’m still hoping we get more insight into Roland’s mystical biography in Arcel’s first movie.
Everything we have been told about The Dark Tower is that this will be a sequel, of sorts, to the books, so it won’t play out along the expected Beam (or path) that we know from the novels.
