I love them, I read the first four (up to Wizard and Glass) maybe up to four times and then the last three once. This is my first time re-reading the whole thing together. And also my first time reading The Wind Through the Keyhole, which King wrote after he had finished the series and fits in between Wizard and Glass and Wolves of Calla. It's patchy but good, W&G is my favourite and possibly my favourite Stephen King book at that.tried those back in my teens. Made it to Wizard and Glass and I was completely spent by then.
I remember the first 3 being really really good.
This going to be a film (series of films), or TV series soon, isn't it?
As for the film thing, last I heard it was Idris Elba as Roland and Matthew McCanaughyghgyghgy as the Man in Black and it was going to be a mix of films and HBO series rather than all films or all TV series. I don't know how I feel about it, it's either going to be amazing or it won't translate at all to the screen.
