Come on... it can't seriously be only me a Tep that have watched it so far?

Either way, I guess I'll start.
Quite possibly the best NewWho special I've seen, and for once I didn't mind the sugar-sweet ending (sure, everything turns out for the best, but it's a very sad best). The best part about it? It was set millions of miles away from London! Yippee!
The writing was good (some cracking lines - "Too big a lie" when the psychic paper turned out to be showing wiggly lines, "Don't go to your room and design a new screwdriver like I did" to young Kazran), with quite a decent story that didn't deviate into the insane. The effects were good (I particularly liked the fish) and the SF elements satisfied my hunger (the very nice ship, I noticed, looked very much like the one that crashed in the Weeping Angels episode(s) last series, and the idea of a planet with fish in the sky amused me), and the music was fantastic (Murray Gold's action theme, as I think of it, came back with gusto, and the singing was superb).
A couple of tiny niggles - when the TARDIS is revealed behind the doors (whent he recording is first being played), you can see the windows through the gap when the doors closed, but they don't fade away with the TARDIS take-off sound effect. Also, I'm not entirely sure about two instances of the same timeline being able to embrace each other - in the Father's Day episode with Rose, we're told that bad things happen (though rather than the past being brought to the future, as in this episode, future Rose sees her past, baby self. I'm wondering if that makes any difference).
However, I really enjoyed it, and may well watch it again.

As for the next series (or, at least, the first half) - looking good! I noticed some sort of Renaissance figures (French?), Nazi's, a strange episode where everyone is covered in tallies and, of course, the two-part episode set in 1960s America.
EDIT: Almost forgot the return of the fez, both in this episode, and mentioned in the trailer! And jammy dodgers.
I wonder if his next new screwdriver will deviate at all from the current new screwdriver?
