It seems the main problem with this movie is that it tries to cram a huge lore and story into 95 minutes. Anyone who has read just the first book would know that cramming it down to 95 mins was not going to end well. The Dark Tower series need to be done with either a mini series, TV show or something along those lines.

A TV series is planned with the same actors I've heard, based on Book 4. 

You can't do Book 4 with the same actors, the Gunslinger is a teenager in that book, and most of the other characters are entirely different people who don't even star in the rest of the series
