Doctor Who: Inferno (1970)

The Radar read

A quieter title still finding its audience, though the rating rests on a thin sample, so treat it as provisional.

Synopsis

UNIT is providing security cover at an experimental drilling project at Eastchester, designed to penetrate the Earth's crust and release a previously untapped source of energy. Soon, however, the drill head starts to leak an oily green liquid that transforms those who touch it into vicious primeval creatures with a craving for heat. The Doctor is accidentally transported "sideways in time" by the partially repaired TARDIS control console into a parallel universe where the drilling project is at a more advanced stage. Thwarted by his friends' ruthless alter egos, he works to save both universes.

Radar blends quality, momentum and freshness into one “what to watch now” number — so a great older film can sit lower than a rising new release. The Quality signal above is the time-neutral rating, which is why an acclaimed classic keeps a high quality score even when its Radar number is lower. Radar outputs are editorial algorithmic recommendations, not objective facts, and may change as signals update. A Radar score is not the same as a TMDB, IMDb or critic rating.
