 "Little touches" – such as the realism of Black's cautious ascent of the Sun God statue, and Scarlet and Blue being on first-name terms (making them "real people, with real names and lives behind their codenames") – are also positively received.What is most to the episode's credit, argues the magazine, is its downbeat ending, which is aggravated by the fact that "Spectrum's efforts actually make it worse".James Stansfield of website Den of Geek ranks "Inferno" sixth in his "Top 10" list of "Captain Scarlet" episodes, praising its "horror movie-style elements" and describing the episode overall as "tremendously fun".
