This is one of my favourite ever episodes of Torchwood. It's such a powerful and hard-hitting hour of television, from Gwen's devastating speech about why the Doctor isn't always there to save the day to those shocking scenes of the army grabbing the children and carrying them away from their terrified parents.

I keep saying this, but this five part story really does feel topical in 2020. I mean, reopening the schools and insisting it's safe for the kids to return even though it isn't - need I say anymore? That's literally what is happening right now! The only difference is the threat isn't aliens getting high on kids.

That moment when Frobisher first learns his kids will be among the sacrifices to the 456, so the government can be painted as the victims, is so hard-hitting also. Anddon't get me started on that depressing montage where he kills himself and his family to avoid his kids' otherwise even more horrifying fate. I could go on forever about just how brilliant the last part of Children of Earth is.

This is a dark story done right. It's not dark for the sake of being dark. It's dark because the narrative commands it to be so. This is the only way Children of Earth can be told.
