This project should've been straightforward: Chronologically you start with the genesis of the conflict between Ronald and the Man in Black, you build your characters toward the conflict aka Last Stand, and you end the movie in the dark, just before the start of the first book. Movie of 2, 2.5 hours, dark, with R-rating. You exploit the potential of the brilliant actors at your disposal.
You just don't do this. Rubbish. I gave it three stars just because of McConaughey and his obviously good performance as the Man in Black.
