What an incredibly depressing episode. Feeling this pit in my stomach, I know why I haven't watched Black Mirror in quite a while.

Cool animation, mid story. But I guess, I'm not a fan of the Predator-formula with humans persevering through dumb luck and questionable ingenuity over these killing machines.
First two storylines were in a cool setting, last one was just dumb with boring "fighting" and an incredibly annoying protagonist who had to constantly spout quip after quip.
