Well, judging by the glorious minute long trailer on YouTube and the BBC site, more than enough reasons to prove that Matt Smith is going to be quite the Doctor to watch for in 2010.
Have we ever seen the Doctor this aggressive towards a Dalek before by new series standards? We certainly have now. Some people have complained about seeing Daleks again but shouldn't every Doctor get them in their first year? Besides from the looks it, it's a small scale story anyways and it's supposed to be written by Mark Gatiss.
I'm going to be in a minority here but I actually love that Eleven and Amy snog and I don't give a shit what the reason is behind it, though it's probably going to be platonic and it seems to be in the River Song two-parter if Amy's outfit is anything to go. I can deal with the Doctor's snoggage bouts but I'm hoping there's more to Amy than meets the eye if you catch my drift. Plus at the end I think the little girl Eleven is asking for trust is a younger version of Amy.
