Ex Machina
By the end of Ex Machina, Ava has passed the Turing Test with flying colors. The AI manipulates Caleb (Domhnall Gleeson), her would-be proctor, into developing feelings for her—only to lock him up and leave him behind to die on the compound as she escapes. Ava, no longer a rat in a maze, passes for human in the real world.
Orphan
Orphan follows a couple, Kate (Vera Farmiga) and John (Peter Sarsgaard), who adopt a mysterious 9-year-old girl, Esther (Isabelle Fuhrman), after the tragic loss of their unborn child. However, after Esther returns home with them, the couple realizes they are in danger. In the end, we learn that Esther is an escaped 33-year-old mental patient with a hormonal disorder that stunts her growth.
