Black Mirror S6 E3 "Beyond the Sea" appears to have gotten relatively positive reviews online, but my friend and I hated it. Every single plot point was a predictable cliché and the plot itself was full of egregious logic holes.
Black Mirror episodes should surprise us or make us see a new perspective, but this story has been done a thousand times in fantasy and sci fi history, and quite a bit more competently too.
This episode was a real letdown.
