Torchwood: Children of Earth

So. Finally have recovered from Children of Earth. While I've got lots of thoughts running through my head about this, there's one thing that's striking me a lot about the whole thing. Don't worry, no spoilers here, except maybe general theme of COE...

...but did anyone else get the feeling that Children of Earth was really just a super-intense and very adult version of 'The Unquiet Dead'? I can't shake that feeling...

Thoughts, anyone?
