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 — 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".
