This film is watchable enough but I must admit to having a few reservations. The story of a nurse who twigs to the fact that a colleague and friend is in fact a serial killer and then has to report him and take part in his capture and interrogation despite him being one of her few supportive friends is based on a real story. Charles Cullen has been jumping from hospital to hospital (in the early 2000s) and seems like a gift: competent, willing to do night shift, etc. For some never explained reasons he also kills patients by putting other drugs in their drip solutions while they are in intensive care.
Amy Loughren, his colleague is struggling to complete a year’s tenure at one hospital so she can become eligible to claim health insurance and get a heart operation. She is battling health episodes and bringing up two little girls.
Jessica Chastain is her usual fine self as Amy, credible and always interesting to watch as she tends to rely on minimal gestures and voice tone to convey her character.
Eddie Redmayne also underplays Charles for much of the film – an almost nothing character – bland, helpful and only at the end shows a pent-up violent streak though he never explains why he killed possibly up to 400 people. Almost more interesting is the clash between the investigating detectives and the stonewalling hospital administrators and lawyers who do everything they can to put obstacles in the way of helping the investigation. Cullen was employed at 9 different hospitals in the area and never properly supervised or investigated.
The shortcomings of the hospital system in which we put our trust and the shortcomings of the health system denying a hard-working nurse coverage for a serious condition show up the appalling healthcare set up in the US at least in those days and this almost peripheral material fleshes out a fairly dull lead plot. Tobias Lindholm chooses to film in dark night scenes or grey winter shades which also make the film somewhat less attractive to follow.
Finally, I asked myself quite what the motivation was to make the film. There have been far better serial killer films around and the tension here is quite low-key. The medical mismanagement adds to the story but is left undeveloped as it was in real life. We are left with the dilemma about ratting on a friend or not and this seems a logical choice here. At least Amy got a happy ending in life.
