The movie goes downhill when Lina sees she is using the alphabet board. Why is she working with the doctor now when he just tried to kill her? Why does Lina want to kill Katherine when she was originally trying to save her from Lawrence? Why does Katherine want to kill Lina in the first place if she planned on outing her with Lawrence, for killing Jamie with her journal. In the end it is made to look like Anna was a hero even tho it was her idea to bring Katherine back to the house and kill her. Was Lawrence into Lina or Katherine? What is his motives? So many plot holes. Is my review confusing? That's what the movie is like!

Locked In is generically a modern Gothic story. British, manor, orphans, illness, love affairs, duplicitous characters, plots within plots, etc. All of that, the movie does well.

Do we need another Gothic mystery of orphaned child becoming entwined with a decaying family and its manor? Probably not. Do the actors move past the 2 dimensional nature of their characters? Decidedly no. Does the story line bring anything new or ingenious to the story? A resounding no.

Part of the issue I see is that the main character is the young orphaned girl and her movement into this family and the machinations of the plot. She's not that interesting of a character. And the narrow focus that the film takes toward her shuts out the other characters from being able to provide much richness to the story.

This harkens to the great movie and story of Rebbeca in many ways. But that film allowed other characters room to play, and the uncertainty of motivations and conniving increased the sense of tension and dread. As a copy or comparison of that, this films decidedly missed the mark. As a display of a Gothic story, it does all right.

Nurse Nicky Mackenzie (Anna Friel) gets a new patient, Katherine (Famke Janssen) who is unable to communicate due to her injuries. She starts talking to Katherine's visitor Lina (Rose Williams). 13 years earlier after the death of Lina's mother, Katherine had become her guardian. At the time, Katherine was a rich and famous Hollywood actress. Her son Jamie suffers from periodic seizures. 3 years earlier, Lina is marrying Jamie (Finn Cole). Dr. Robert Lawrence (Alex Hassell) is treating Jamie.

This feels more like an old timey soapy romance melodrama mystery. I like all these actors. I am slightly intrigued with their characters. I would change one thing for sure. Nicky Mackenzie should be a cop investigating Katherine's incident. As a nurse, she adds no tension to the story. As a cop, she could uncover some sort of foul play and the audience would be more invested in the mystery.
