I just watch the first ep. and I really enjoyed it. The guy playing the Doctor did an excellent job of getting the character right. Overall, it was updated, but still felt like Doctor Who (nice to not see a rock quarry for once). I like that it's not a serial. The conspiracy theory stuff was a lot of fun, though it'd have been nice to have seen pictures of earlier incarnations.
I liked the companion. I think Comickaze is very wrong in his assessment. She's definitely an everyman (everywoman?), which is what the Doctor's companion needs to be. She certainly didn't come across as stupid or incompetent, just your average person (albeit, a pretty hot one) who managed to keep a fairly level head through-out the crisis (especially compared to all the other humans). I also thought she was very well acted.
I'm definitely looking forward to seeing more.
