donster-1 Not sure why this episode received such negative ratings. It's my favorite episode of the Black Mirror series. I't been a while since I've seen it, so i need to go back and watch it again to provide a more detailed review.

ashsmith-108-818828 Wow! This episode left me on the edge of my seat the entire time!! I loved the post apocalyptic feel to it! Very nice, Black Mirror!

Jitendra Kotai The Dog shaped robot was ferocious and scary. The execution is fantastic, The screenplay is paced perfectly for a thriller. The Lead actress gives out a phenomenal performance. You cannot take your eyes off the screen and you are glued to the screen in anticipation of thrill. I think so far the best episode in Season 4

boris-922-878361 This is an episode where the punchline really hits you hard. I dare you to watch this, hate it, see the very last 20 seconds and THEN hear the first five minutes with dialogue again. "This has no dialogue" "This explains nothing" Yeah, it might be TOO artsy to make the dialog from the start really be totally frightening only when you know the end because 35 minutes is over the attention span of some viewers. I really expected at the end a clumsy reveal about the source of the security robots but what you get instead really shows you HOW desperate things have become.And I keep this spoiler free although a real discussion could not be done without spoilers.
