Well its part two of the River meet Pond meet deadly stone angels as the story concludes in "Flesh and Blood"

Nice a bit of mystery in doctor who and the crack has now been explained halfway though the show , alot of theorizing on this episode with the pandorica and the crack and who river killed , Which makes it a top notch episode, as now the timelords are gone we need some nice big arcs and also some reasoning for he Doctors journeys and this looks iike it is just starting to get going.

My only hope is the crack is taken all the way through to the second season.

Well what an enjoyable story, really enjoyed it. Quick paced and with some rather intriguing references. Those angels are dark!
