Just finished the first book. I thought it was ok but some of it was a little vague/confusing (I usually have great reading comprehension) and I'm not a huge fan of Stephen King's writing style. However, I'm going to continue to read because I find a lot of the concepts intriguing.

Also, apparently universal has slotted a major deal to produce The Dark Tower as a trilogy with a mini tv series in between each movie to fill in the gaps. Ron Howard is supposedly the director and Roland's top two potential actors are Javier Bardem (bad guy from no country for old men) and Vigo Mortenson.
