It was pretty good, answering a few questions.
Rory = awesome
It was a nice twist to have Melody be the one who got her parents together, as well as named after herself.
Whilst it was cool to see a slight reference to the Terminator with the glasses being taken off the Nazi, it was a missed opportunity to not have Melody say 'I need your clothes, your boots and your motorcycle', although she did say something similar
From the name people were expecting something more focused on Hitler, what we got was an arc heavy story where Hitler gets locked in a cupboard as soon as he was introduced
I think they may be bringing the series back in line with the classic broadcast times. The show started on November 23rd, so the 50th Anniversary show needs to be on then to properly mark the occassion (and it is a Saturday in 2013).
Next year, they show half the series around Autumn/Winter, then the rest in the Spring. And then repeat. Something like the 50th anniversary which will inevitably be epic and nostalgic would probably be used as the finale to the first run of the series.
