Des
Des is a pretty haunting story. Oddly tells it in separate three episodes instead of a feature-length (truly not necessary) that finds opportunities to go back and forth between the detective and the biographer in their experiences with Des. It does enough to detail the information thoroughly, especially with David Tennant selling his performance. It's not the most entertaining crime biopic as it teeters on being pretty standard, but it still pretty well-made all around.
