No really, Flesh Eating Shadows = Far scarier than Weeping Angels.
AND THE GHOSTING. It was a bit like how Astrid's essence/personality/whatever was stuck in the teleport in Voyage of the Damned. But that freaked me out too. Ahhh! The Moff has finally given me a good fright as far as alien monsters go.
So yeah, I really loved this episode, if you couldn't tell yet. It's set on a planet that is a virtual library! And the monsters actually scare me! And the fact that I'm not entirely sure what's going on makes it all the more fun. The unpredictability is a big plus in my book, particularly when it's kind of obvious in many other episodes how the plot's going to proceed.
Maybe the only quibble I have is that the Moff got River Song wrong. Her name should actually be Benny Summerfield, y'see. River Song wasn't even onscreen five minutes and I was trying to figure out whether or not it was Benny under an alias. Alas, it's not. But just because she isn't Benny doesn't make her less awesome. I heard some amazing griping about the character in the fandom after this episode (most of them Rosefen, no doubt), but I'm not buying it. In fact, I'm enormously excited at the prospect that she'll turn up again, after this story arc. And she will turn up, because Rusty's called her 'one of the most important characters we've seen in the series', but probably not while Tennant's still the Doctor.
More thoughts when I see Forest of the Dead next week, methinks.
