“The Dark Tower” (** out of four) was a lumbering adaptation of the Stephen King series about an eternal battle between the heroic Gunslinger (Idris Elba) and the villainous “Man In Black” (Matthew McConaughey) and how a young boy (Tom Taylor) becomes caught between them and caught in the fate of the world in the balance. Too much mumbo and too much jumbo and not enough fun although McConaughey’s entertaining performance makes this worth watching for at least a few minutes. Final showdown is exciting but takes far too long to get there.
