My head began to throb as I watched an extended Cinemacon product reel for Nikolaj Arcel‘s The Dark Tower (Sony/Columbia, 8.4). I was going to say “there’s nothing more boring than battles between absolute good and evil,” but then I remembered Shane (’53), which is almost a black-and-white thing. But not quite as it acknowledges, like any decently written story, that we all have our reasons. Even Donald Trump, the most flagrant manifestation of evil this side of ISIS, has a motive or rationale of some kind.
