I'm strangely at ease with Matt Smith as the Doctor. Despite his slightly freakish looks, there's much more naturalism to Smith's expressions and movements, which I appreciate a lot.
It's definitely preferable to Tennant's cartoonish mugging (which I don't blame on Tennant, he's obviously a superb actor, it's just that his Doctor was written/directed in the laziest of ways).
So they're bringing back Silurians. Huh...kind of a weird, uninteresting race to bring back, but whatever. I'm all for the new season...bring it on. Moffat is already touting the fact that he wants the show to get back to being more like Doctor Who i.e. self contained stories without shit tons of referencing older episodes and events, nowhere near as much soap opera-y bullshit, and more stories taking place in space as opposed to every thing bad in the universe constantly revolving around the Doctor's little group of in-laws or whatever.
That sounds promising, but I'm concerned Smith is just Tennant with no eyebrows.
Also, I hate these trailers that are just ten milliseconds of action from one thing interspersed with ten more from other things. Give me a trailer where I get a full summary and then I don't have to watch the actual show.
Still, the show could use a doctor who stays with the series for a VERY long time. I feel like neither Eccleston or Tennant were quite... Iconic enough.
Although, maybe comparing them to Tom Baker is unfair.
Steven Moffat has been the consistently best fairly regular writer on this show. By contrast, Davies has been the worst. Smith may look like a too-young doof, but Moffat deserves the chance.
