For all the apparent deviations from the source, I really hope it's good
I want the whole story to be told, with the visionary differences the director has from king's original, rather than tripping spectacularly in the first film and subsequent films being quietly shelved.
Long before reading the Dark Tower, I read a young-teen series called the Darren Shan Saga, a story about a boy being turned into a half-vampire, and his introduction to, and life within, the expansive yet hidden vampire world (something akin to Harry Potter's introduction and life with the same kind of expansive yet hidden Wizarding world). Being the exact age the series was targeted for, I was wholly engrossed, reading the whole series in direct succession about 3 or four times. Cut to about 2 years ago, and my younger sister is at that same age. So come christmas, I decide to buy her the series, and just like me, she absolutely loved it.
My point is, at some point I learned that there was actually a film made based on the books. You might be unfortunate enough to have heard of it, maybe cursed enough to have SEEN it: Cirque du Freak: The Vampire's Assistant. Anyway, we watched it together, and both agreed it was god-awful. Not just because of the huge deviations from the source (the biggest one for me being the atmosphere. They turned a thrilling drama into a goofy comedy ffs), but the movie was, in all aspects, garbage. This movie came out 7 years ago, now, and there are precisely NO plans to make the rest of the story into film (the movie covered about 1.5-2 of the 12 books), which is a shame, becuase fixes could have been made. Again, look at Harry Potter: Not that the first 2 films were bad, but the change in atmosphere, setting, theme, etc, from movie 2 to 3 is pretty striking, and all for the better IMHO.
Basically what I'm trying to say is, I don't want to wait all this time, to watch the film pass hands in an eternal limbo, to only see one terrible movie, and the rest of the films dropped like a wet fart. Whether I like the films or not, I'd still rather see the WHOLE, FINISHED story.
Plus, I'm interested to see if Eddie and Susannah will even be incorporated into the story, and if so, who'll play them.
