The script has plenty of quite intelligent moments and unexpected reversals. Arguably the most effective of these was the handling of Cooper’s father’s Alzheimer’s – having set the audience up to expect an apparition of the father, Charlie Brooker expertly subverts this by presenting a far subtler rendition of Cooper’s fears about his own mental state. It’s possibly one of the most intelligent scares of the episode, and by that token the most meaningful; certainly, it stands head and shoulders above the CGI jump scares that proliferate the rest of the episode.
My review of Black Mirror Season 3′s second episode, Playtest. It’s an attempt at a more overt horror story than they normally go for, but sadly, it’s not one that connected with me.
