Review of The Beast Below (Doctor Who 5.2)

I really enjoyed this episode while it was airing, but felt as if I'd missed some bits, so this evening I went back and watched it again. And really enjoyed it the second time too. I can't say why, exactly, since it's not exactly an original story and it wasn't filled with witty lines or with amazing characters or guest stars, but… I just liked it.
