Yes, we've seen the first few episodes, but haven't had any luck finding the next one in sequence (not that it matters, really). They are certainly a bit disturbing, but make you think, in a good way. Both DH and me spend most of our waking hours on a computer, and his sleep is certainly adversely impacted by not packing it away before bed. Reminding ourselves of the negative physiological and psychological impacts we experience from being on screen all the time is good - except the screen itself is doing the reminding on Black Mirror!
