Wow. The first fantastic chapter of what I’m sure will be a grand fairytale. The only episodes of Doctor Who that I’ve seen* that are better are the ones from the previous seasons that were written by Steven Moffatt.
The acting was far and above previous efforts, though I like David Tennant’s work quite a bit. Matt Smith turns it up to 11.
Also, Amy Pond was infinitely more interesting than the previous companions I’ve seen. Right now, I think it’s her story, not the Doctor’s.
* Admittedly, I have seen very little Doctor Who. I just never have liked it much, until I saw the Steven Moffat episodes. And I only gave those a try because I love Coupling so much.
