review, writer Fred McNamara criticises the story's "two-dimensional execution", arguing that its descent into a "waiting game" as the SKR4 draws closer to Earth makes the episode an "unfulfilling watch". Noting that "Inferno" was one of the last Captain Scarlet episodes to be made, he suggests that its unexciting plot demonstrates how, "as a story-telling vehicle," the series had "flown as high as it could fly." He adds that Spectrum's powerlessness against the SKR4 makes them tantamount to "hapless bystanders", calling this portrayal "oddly compelling". He regards the ending as allegorical, stating that the destruction of the ancient temple triggering a landslide that obliterates the desalination plant represents "humanity's spiritual past crashing down on humanity's technological visions". Commentators Chris Drake and Graeme Bassett suggest that SKR4 being under the control of an agency called Euro-Space shows that the episode's writers were "keen to establish the existence of a European space operation in addition to the obvious American space programme".
