Tobias Lindholm’s The Good Nurse is a film based on the real-life case of serial killer Charles Cullen. Eddie Redmayne and Jessica Chastain star as nurses Cullen and Amy Loughren, respectively, delivering a very strong dynamic between them. Added to the marvelous acting, Adam Nielsen’s editing keeps the story flowing with ease, taking us from the rigorous police investigation to the more mundane moments of the story within a good balance. But The Good Nurse isn’t able to find its footing. The overall tone of the movie is as gray as the dull hospital rooms in which the story takes place, taking away the energy from what would otherwise be a stellar thriller. Great performances and excellent editing can’t make up for the film’s lack of style, displaying a great deal of potential that ultimately leads to disappointment. Amazing concepts that were very close to a well-done execution plague the film’s script and direction. Nevertheless, whatever Lindholm takes on next should be on everyone’s radar, given his ability to obtain great acting from his leads and establish a cohesive atmosphere within the movie, even if the projects’ elements don’t make a good match.
