So I want to talk about one specific episode of Stargate.
In that they contact a alien civilisation that heals all diseases on earth but makes all the women infertile to genocide earth and take over the planet.
All of the main characters then sacrifice their lifes to make sure earth never contacts the civilisation with a short notice that gives no clues about the circumstances making it impossible for earthlings to evaluate how to react to the medicine.
I don't really know where to go with this but the episode has been in my mind lately and I thought better than let it drown in the general. You can turn this into a general if noone else wants to discuss the episode.
