Query: Excellent!

This episode along with "The Stolen Earth" are probably two of my favorites. I love how they reunited everyone to fight the Daleks. Sad to see David Tennant go, however. He was great as The Doctor. And I'll miss Catherine Tate as Donna too. I have not watched seasons five and six yet, but this season is probably one of my favorites so far.
