This was a great episode. Funny, perfectly paced, reinvented the Daleks, gave Smith even more choice time to show his stuff, and a WWII dogfight in space. It was also entirely unexpected, given the heavy emphasis on the Daleks' deception in the advertising.
I disagree the best two parter of the current run was Lost Earth and Journey's End both Dalek episodes. I saw the first Matt Smith episode. The crack in time is interesting as well as the new Tardis, the rest is just there. Loved the Dr.Who through the years montage.
I DVR Late Night every night (but set it to save only the previous night's episode). I usually don't watch the episodes before they get removed from my DVR but almost every time I *do* watch, the show has a pretty decent musical performance.
