TL;DR - My god they weren't lying when they said Children of Earth is really good

Day Five is in some ways the quietest Children of Earth episode. We sit in long, deliberate silences. Screams come through muffled, if they come through at all. The devastation after the storm. It is breathtaking to watch.

As far as series finales go: oh my god. We get a couple of extra blows to drive home Ianto's death last episode (no, we never really did know him much, did we? Hell!, he was barely a character in s1!) Jack and Gwen's relationship reaches its natural conclusion, and I think we all know who (or Who) he learnt the trick of Leaving Behind People Who Need You from. Peter Capaldi as Frobisher is once again the star of the story, we've watched his breakdown and now we get to see him truly at rock bottom.

This episode is also interesting politically. It, of course, hits different post-2020, but then again politicians have always been slimy liars looking out for themselves first. What's notable is how Andy - a policeman, puts his foot in it sometimes but ultimately is a good man because of the work he does - joins the fight with the people on the council estate against the army. The army have always been The Bad Guys here, but the police have been good, helpful; Gwen was police and she's our beloved if flawed main character!

Except in this instance, Andy very deliberately removes his police hi-vis before he can become one of the heroes.

I just found it interesting.

I also find it interesting how they've got another series of Torchwood after this, such an obviously show-ending finale. Admittedly, I've heard nothing good about this series, so it was probably a bad idea all around, but I have to wonder who greenlit it.
