Out of those three stories? Blink, easily. The Weeping Angels are probably my favourite Doctor Who villain up to date, and that interaction across time and space between the Doctor and Sally was mind-boggling, in a good way. The other three were very good as well, though I'd say that the closing trilogy is one of the weaker links of Season 3, actually. It's not bad, and the Master is amazing, but it feels a little like it's trying to cram too large a scope into one story.
As with the hand, I thought that it was the hand of the woman that worked for the Master, that you'd seen during the earlier episode, where Martha's mother gives her phone to her - I think she had the same nails.
Also, will it be explained where the sound of drums come from, in the Master's head? 'Cause I'm guessing that it's not just a byproduct of looking into the vortex, otherwise the Doctor would have probably known about it.
Also, today's episodes! Beware, today was a long day of Doctor Who.
Voyage of the Damned: Great. I loved the setting, and Kylie did a pretty good job as a companion. It was kinda clear that Max Capricorn would be involved somehow, and I quickly got the impression that he's behind the whole thing, even though I would have never, in a million years, guessed the resolution. Probably my favourite Christmas special so far.
Partners in Crime: So-so episode, I guess. It wasn't bad, but nothing about it really wowed me and that moment with Donna at the door and the Doctor at the window was downright stupid. The Adipose were kinda cute, though, and I felt a little like punching the air when Ms. Foster dropped down - I don't know what it was, but she really got under my skin for some reason.
The Fires of Pompeii: Great episode, once again. I loved how it wove into the historical events, and the Pyroviles were really an interesting villain. I can't pinpoint the exact reasons - there was nothing really especially special about this one - but I just loved this episode to bits.
Planet of the Ood: Amazing. I was really happy that the story of the Ood, of which I was curious after The Impossible Planet / The Satan Pit was expanded on, and when I found out the real origins of the Ood, I felt pretty sorry for them. The ending was brilliant though, that dick deserved what he got.
The Sontaran Stratagem / The Poison Sky: Very good. I loved it that Martha returned for this one (I think I prefer her over Donna - not sure about Rose) and the way that the suspense was build and held was absolutely brilliant, both with regards to what the Sontaran were actually planning and the Martha situation. Also, Rattigan was a dick, but I guess he did redeem himself at the end.
The Doctor's Daughter: Something about this story rubbed me the wrong way... I liked the premise, but there were several plot-holes here that really bothered me. Why did they shove the Doctor into that machine, without any tests before? And why were they so quick to lay the weapons down at the end, after the Doctor basically told everyone that everything is a big lie? Why was that Hath ready to sacrifice himself for Martha so quickly - weren't they as entrenched in their hate as the humas were? I guess, all in all, it felt like the character development was incredibly rushed and a little unrealistic - maybe by expanding on this a little and by making it a double episode, it would have worked better. I liked Jenny, though, I loved how she put the Doctor into his place sometimes - that, and she was SMOKING.
The Unicorn and the Wasp: Maybe it's because I love Agatha Christie, but I absolutely adored this episode. The two interweaving stories of the wasp and the unicorn were pretty great and I loved how they tied together. And that moment with the Colonel confessing was hilarious.
Silence in the Library / Forest of the Dead: Oh. My. God. I love Steven Moffatt, and this was a serious mindfuck episode. For a long time, I had no fucking idea what was actually going on, but the way that it was resolved was brilliant. And the addition of River Song was amazing and added another dynamic to this already amazing story. Also, when I heard that the Doctor's name will be unveiled, I nearly fell of my chair - isn't that, like, the Doctor's best-kept secret? I did find out that there is an episode called The Name of the Doctor, so I am really looking forward to that one now.
