I thought it was a really good episode. It does well to strike that blend of weird, yet very human that I watch Black Mirror for, while also showcasing a strange scenario that can only ever really occur with the sort of technology that is at the core of the episode. At first, when they were just gaming, and even into the second gaming session with the VR, I thought "Aw jeez, another VR video game type of ep", but things quickly took an interesting turn.
I reckon a lot of us have probably participated in those weird and far-fetched talks with our friends about what we'd do in a virtual environment that wouldn't be possible in the real world, and we likely haven't given it thought much deeper than a half-joking "I'd fly", or "I'd fuck my waifu". This episode, however, does well to showcase how something like that might affect people's real life mindsets and behavioral patterns as a result of such a thing actually being possible. People are weird, and the scenario depicted in the episode where two dudes decide to fuck in a game just to see what it'd be like, then get addicted to it, was actually pretty compelling. Does it count as cheating? Is it gay? How does it feel for the dude playing as a girl? I liked that the characters asked and answered those questions.
In the end, it turned out that they weren't even gay for each other in the real world, just addicted to the experience of getting their rocks off in an odd way: playing a fighting game, and using their in-game characters to screw instead of fight. Lmao
Also wanna heap some praise on the dinner scene between the two near the end of the episode, which was both dramatic and funny. "I fucked the polar bear, man!"
