Normally I feel that critics are looking to say nasty things about anything that isn't pushing the limits of art to the point where no one can understand that movie. I focus on films purely from an entertainment point of view - I am not a film student, I have no idea about cinematography in an educational sense, only from a "oooh, i like that!" sense. That being said, this movie did not do it for me.
I did not read the books. I tried to read one of them because a friend of mine kept raving about the series of books and telling me how amazing they were. I think I made it a few hundred pages in before I gave up. However, the people who did read the books almost unanimously hated this movie and claimed it was a lazy adaptation of an extremely complex series of books.
The plot involves a young boy who has visions of a "man in black" who seeks to take control of a tower and then destroy it - this will somehow bring ruin to the world - and a gunslinger that seeks to stop him. The visions are very lucid yet this is written off as trauma due to his father's death rather than him being able to see the future - which is ludicrous that a professional psychiatrist would ever come to that conclusion.
However the boy finds a portal to another world and it turns out his visions were correct. Big surprise there. This is where he meets the gunslinger Roland Deschain (Idris Elba.) Now I am not going to get into details about what happens next because I will likely over-summarize and simplify the film and this will completely spoil it. Basically Idris Elba and Matthew McConaughey did they best they could but I can't imagine who this would be entertaining to.
It doesn't make sense to anyone unfamiliar with the books and for those familiar with the books it skips too much of the content of the books. I can definitely realize that director Nikolaj Arcel was facing an uphill battle when he took on this project.
Overall i would imagine that they were happy they turned a modest profit on this film and would likely rather we all forget that they ever made it. I am sure the fanbois would have preferred this was a trilogy but for me, I am happy that it never was. I give it decent marks based only on the effects being pretty dern cool.
