THE new Supergirl movie examines the brutal quandary of whether it is better to allow the Kryptonian race to die out or to f**k one’s cousin. 

Though not revealed in the trailer, the bulk of the film is a debate between Superman and his cousin Supergirl about whether they have the right to condemn their people to extinction just because the thought of doing it gives them the ick.

Movie reviewer Tom Booker says: “Superman presents a strong argument for procreation, saying that ethically they owe their people the chance to live again, citing all the good he has done for humanity and which their descendants could further.

“Kara replies that what if mingling their related genetic material creates a monstrous superbaby, who would the next generation have kids with anyway, and also ew.

“Superman counters with their moral duty to provide Earth with protectors and says yes, they would need to do it the old-fashioned way because his super-sperm would shatter any test tube.

“She says what about Lois Lane and Superman says Lois doesn’t have to know. Then blows it completely by suggesting she could work up to it by giving him a handy.”

Fan Oliver O’Connor said: “Finally a relatable superhero film with conversations like those we’ve all had in real life.”
