Thoughts?

I thought he was pretty good (he's crackers but not a complete fruit cake). The episode was decent as well in my opinion. Later episodes should be very interesting.

Was pretty good, though think it's probably going to get better. Nice to see a distinct lack of present-London in the preview, that gets boring quickly.

Also

Episode 4: The Time of Angels
Episode 5: Flesh and Stone

Weeping Angels are awesome. And they are going to have more powers than we've seen before (and for all we know so far, they are psychic, can move really fast, and can kill you in a single touch) so you're not safe from them just because you can keep your eyes open and looking at them.
Also rumoured to be the same 4 angels that we saw in Blink back for revenge, as it is shown in Blink that despite them looking at each other, once the bulb goes out they can't see it each other and thus move unhindered once again but rely on their psychic abilities to find prey in darkness (or just guess and head in that direction). If they could see in the dark, they wouldn't have all 4 of them been able to simultaneously attack the 2 heroes without covering their eyes.
