From this morning's Guardian Dr. Who blog:
I'm just going to come right out and say it. Flesh and Stone can lay credible claim to being the greatest episode of Doctor Who there has ever been. That's better than Genesis Of The Daleks and better than City Of Death and better than Tomb Of The Cybermen and, yes, better than Blink. It's just ridiculously good – so much that there's scarcely any point in picking out moments because there was an iconic sequence every couple of seconds.
