To be honest, it didn’t take me long to suspect what was going on in this film. I saw that the lady who arrived was very emotionless and it made me suspicious from the start. The hints kept coming and most audience members will figure out what is going on before they are shown the truth. There was also some hints at Morgan being a lesbian with the behaviorist. It was hard to pin down exactly the degree of relationship between the two and really, we were never fully told.
Overall, yes, it is a good film. It does more with plot and suspense than it does with blood, guts, and gore. So its not a traditional horror movie where the cyborg goes crazy and murders everyone. I mean, it is that, but the plot focuses on the build up and does so by withholding facts from the audience until the current situation has nearly explained it for you without the need for a flashback.
A lot of questions are left unanswered by the end of the film and the audience is left to make their own conclusions. Sometimes this works, other times it doesn’t, I think for this movie, it flowed well with the rest of the story. The acting is great as well, like, the emotion these people display is astounding. I would think this was done to further demonstrate the different between the artificial human and the real. I’ll leave it up to you, to figure out which are which. But yes, this movie is original enough to be worth seeing.
