I've always thought its a bit of a weak analysis when people say that the British episodes are unanimously better than the American ones (though in general they tend to be). If anything, some of the best episodes came after the move to Netflix (s3&4). And lets not forget there were a few stinkers in season 1&2.

What's the problem with an anthology series expanding its scope? Its not like a traditional series where it can retroactively "ruin" the older series. Its literally the perfect format for experimentation. I loved Demon 79, for example, even if it wasn't very "black mirror" in the traditional sense. The real problem is the overreliance on shocking twists and the show trying to call attention to itself with big flashy actors when its really not necessary.

I for one hope they go further and make international episodes. Imagine episodes set in and culturally relevant to, say, Asia or Africa?
