Doctor who series finale

I really enjoyed the finale. I didn't think it was as good as the first half of the two-parter, but still very good. (As someone said, it can be easier to set up something insanely dramatic than to live up to it.) In fact, I looking back, I see every episode of season #4 was good (I think the weakest was the first, although in retrospect, I'm not sure, it was a bit flat, but it also had quite a few classic moments), as was every episode of season #1.
