Black Mirror Season 4: Every Episode Ranked From Worst To Best

6. Metalhead

Even the worst Black Mirror episode is hardly awful, and to that end Metalhead is a gorgeously shot, well-acted action thriller, yet ultimately falls short with its lack of incisive social commentary, brief run-time, inconsistent pacing and simplistic narrative.

Not much more than a straight-forward chase between a woman (Maxine Peake) and a relentless, mechanical dog, this 40-minute sprint manages to be suspenseful enough, but with long stretches of wordlessness, a general lack of complexity and a final twist that's neither surprising nor particularly clever, this doesn't feel terribly deserving of Black Mirror.

Still, director David Slade makes good use of monochrome and the robot CGI is surprisingly excellent, though the dip in quality from the prior four episodes is extremely noticeable.
