Out of reason conclusion

Rating: 6/10 (2 January 2020)

The possibility of the main character being replaced in the mirrored room is considered from the beginning, because she started to act differently after she left. However, this possibility is discarded as she explains to her husband what she saw in that place and by the way she shows restlessness and fear by the signs she sees during the vacation, leading to the conclusion that she wasn't replaced, only became traumatized by the encounter with her other self. As the movie progresses, the dialogue between the main cheracter and her doppelgänger doesn't leave a possibility of that original hypothesis being what really happened, once the evil copy talks as if she lived in the underground her whole life and explains to the main character the origin of people's copies and how they live as if she didn't already know. What seemed to be out of reason in fact is revealed as the plot twist, but a twist that doesn't shock and only leaves question marks in the viewer's head.
