Doctor Who: 10 Worst NuWho Villains
5. The Eaters Of Light (The Eaters Of Light)
Fittingly, the worst episode of Series 10 also includes the worst villain of Series 10: the Eaters Of Light.
Peter Capaldi's final season is stuffed to the gills with unique and interesting monsters - the Monks, the Emojibots, the Ice Warriors, the Mondasian Cybermen - and consequently, these grey four-legged reptiles feel like a massive step down.
The Eaters Of Light have a pretty nifty ability in that they can "drain" the light from their victims, but since we never get a good look at this power in action, it feels like a waste of a strong idea. Those aforementioned reptilian looks also make for a villain that isn't really scary, and overall, the Eaters are used so sparingly that it never feels like there's much of a threat while watching the episode.
On the upside, the CGI used to bring them to life is excellent by Doctor Who standards (barring one questionable shot of an Eater running outside in the dark), but on the downside, that's really all they have going for them.
