The complaints came after a scene in which Madame Vastra helps to keep her wife Jenny alive in response to a threat from droids that only move when they can sense breath.
One tweet suggested that “the BBC wants to become a porn channel,” while another said that “the Lizard/Lesbian kiss was ‘unnecessary.’”
However, while some viewers were upset at the thought of two women kissing before the 9pm watershed, the majority of tweets were overwhelmingly positive.
@toddlerlex pointed out that “some parents are okay with their kids watching Dr Who's organ stealing robots & impaled body…Lesbian kiss? Complain to Ofcom! Ridic.”
It has also been noted by various commenters that the “lesbian kiss” was essentially CPR and was actually an inter-species kiss.
