BBC could possibly write to her and let her know how the story resolved. After some debate as to whether the letter was a journalistic trick to uncover advance story details, Kneale eventually decided that it was genuine, and allowed Cartier to send a reply outlining the storyline's conclusion. Following episode six, some viewers wrote in to the BBC concerned at Quatermass's survival, as he had not been seen to definitely return to Earth in the experimental rocket ship. The BBC's own website regarded Quatermass II unfavourably when reviewing its DVD release in 2005. "The script is too often let down by the production's rougher edges. Your heart will break halfway through episode six as it all falls apart. And then there's Monica Gray [sic] – less an actress than a finishing school on legs." Writing in The Times in 2006, Morgan Falconer claimed to find racist undertones in the serial. "Quatermass, for instance, often seemed to have an unhealthy preoccupation with blackness, a barely veiled commentary on racial change in Britain. In one scene in Quatermass II, the Professor stands outside a pub and watches the sky fill with dark asteroids. 'They’re coming in their thousands,' he says, 'this is it.'" However, this interpretation of the serial is not widespread, and is undermined in episode five where an Irish immigrant helps Quatermass sabotage the aliens' food supply system. In any case, it is in direct contrast with Kneale's deliberate attack on racial intolerance in Quatermass and the Pit. Speaking in a 2003 television documentary about Nigel Kneale's career, the writer and critic Kim Newman praised the underlying themes of Quatermass II, and their particular relevance to the British way of life. "Quatermass II is the British Invasion of the Bodysnatchers, but I don't necessarily think that's a bad thing... What Quatermass II does is take that metaphor and apply it to the specific conditions of Britain in the 1950s; not just the Cold War paranoia, but the traditional British grumbling resentment of bureaucracy as represented by the council, or in this case big business." The British Film Institute's "Screenonline" website also offers praise in its analysis of the serial."With its tale of an invasion by an invisible enemy indistinguishable from ourselves, Kneale's story tapped into contemporary fears about the 'red' (i.e. communist) threat, although in a less direct way than the American science fiction films of the 1950s, including
