Much of the true history of the story was changed, which I do not understand because the true story is fascinating. What the book does very well that the movie does not is to make Pikeville and its cast of characters come to life. The setting does not play a great part in the movie, though. And the Kentucky accents and colloquialisms are not great, to be sure.
Emilia Clarke did a very good job with the material she was given, but the script does not quite capture the true Susan Smith very well. Nevertheless, Clarke worked superbly with the material given to bring the troubled, tragic Susan Smith to life. Johnny Knoxville is surprisingly good in his role as Cash. Other important characters, most notably FBI agent Singer, were barely relevant in the movie. Jack Huston was passable as Mark Putnam, and the script and acting actually did a good job presenting Mark's side of the story at the end. However, for much of the movie, Putnam's character is dull, lacking personality. That is more the script's fault than it is Huston's.
All in all, this is a movie worth watching if you're familiar with the story, but it's far from perfect.
