Black Mirror - Every Episode Ranked From Worst To Best

13. Playtest

Fans of Charlie Brooker will probably be aware of his affinity for video games, with Playtest serving as a sharp commentary on the potential perils of mind-expanding augmented-reality technology.

Ably helmed by 10 Cloverfield Lane director Dan Trachtenberg and touting a solid lead performance from Kurt Russell's son Wyatt, this isn't the most sophisticated episode, but as a fun homage to gaming culture - complete with references to Resident Evil and Bioshock - it's a breezy, suspenseful hoot.

The CGI spider is a little rough, but the avalanche of reality-bending twists in the final stretch is great, pulling the rug several times just when you think you've got things figured out. If you're not a gamer, though, mileage may vary.
