Seems like a horror movie... This is one of those episodes whose rating I simply cannot understand. And I'm not going to follow the others who claim that this is a masterpiece because it simply isn't, far from it actually, but on the contrary, I say that it is way too overrated for what it depicts.
Let me try to explain myself a bit. In a post-apocalyptic world where robots hunt humans "for a living", we find a group of three whose seem more or less determined to enter a storehouse in order to find a specific box for someone whom they know that has only o couple of days left to live. So they seem willing to sacrifice themselves in order to get that box. You might think that they would do such foolishness for something important, but we later find out that the whole risk that they took was only for a teddy bear.
Let's say that I can accept this premise (that someone in their situation, in such a dangerous wasteland and in their position of being hunted by deadly robots); although I would do this with great sacrifice, as I find it too hard to believe that somebody mentally sane would actually do that. In this case, it is simply impossible for me to understand what was she (the main character and the only one remaining alive from her party of three) thinking of with every single action she took in order to get back to base. You can add here almost every action she undergoes, from staring without any thought of running when her colleague is slaughtered by a robot to speaking on her walkie-talkie just to send some irrelevant messages while risking exposure, or even going to wash her hands after touching a putrefied corpse instead of running away.
I read plenty of comments by other people saying that humans have feelings and that this is the only thing that separates us from robots, and they are right, but I also know that humans have a basic survival instinct, as animals, and are willing to do anything to survive, especially when put into extremely harsh situations as the one depicted in this episode. Thus, all their actions which were emotionally derived couldn't have all been present at the same time to all three characters. I simply cannot believe that. Furthermore, besides feelings, we also have a brain, and intelligence, which should suppress such ridiculous decisions at least from time to time.
Bluntly, I saw a bunch of people who seemed to be in a dream or something, who don't realize that they put their own lives into jeopardy (or simply don't care about their lives) for a pointless toy and don't seem willing to do even something remotely intelligent in order to survive. They, and especially she, seem determined to do whatever foolish sentimental action in order to get caught, making the viewer even wish they get caught faster as there isn't any point of prolonging the inevitable death; thus, ending up wishing this as a viewer explains pretty clear how my experience with his episode was. I can even associate it with most horror movies, which have the same traits as this one, from a bad plot to ridiculously stupid characters.
