Evaluation of High Maintenance plot twists

The first plot twist has an element of surprise to it, as we are not expecting it, but it is quite logical. at the beginning, both of the characters say and do things in quite a mechanical way. Particularly the man who looks pale and emotionless, although he eats, drinks and smokes , all of which are red herrings, as these activities would not be expected from a robot. Initially, we make the assumption that the film is in the drama genre - the wedding ring is a misdirection as we think the drama is a conversation between a wife who is unsatisfied with her marriage. But we soon discover that it is a sci-fi film about robots. It is a flip of the characters and story's situation because up until the point where the woman turns off the man by the switch at his neck, we are unaware that he is not human. 

The second plot twist is arguably the best one and is unpredictable regardless of the foreshadowing. The line, 'mechanical sex' between the original pair foreshadows that they are robots whilst also unhappy in their relationship. The main hint that the main character could be a robot is the repetition of dialogue and behaviours in the second half of the short film, after the first robot is turned off and the new one is delivered. Additionally, the two women who deliver the new robot behave in a somewhat automated way. The aspect that throws us off and acts as another red-herring is the emotional behaviour of the wife in the first half in comparison to the monotone husband.  The story's ending is perfectly executed, as when the new husband robot turns off the woman in the same manner as she turned off her previous husband, the film incorporates Checkhov's gun through the repetition of the same action, as well as poetic justice because the wife is potentially getting what she deserves. The second man initially seems more like the first but changes his attitude towards her in a more interesting manner, he is smooth up until the point where we see him switch her off and go back to his normal state by smoking and watching TV(just like the first). To add to the mis en scene, there are diegetic robot sounds once know they are both robots. There is only one form of non-diegetic composed score which appears at the very opening and again when she is choosing out her next robot husband, which shows the development in the storyline. It doesn't result in a happy ending, but results in the reveal of the second plot twist, which is highly effective as the film ends unusually so it leaves the audience in shock.
