"Blink" -- Freaky statues! (silly Doctor.)
"Utopia" -- Good thing they had Jack along.
"The Sound of Drums" -- Oh, Martha.
"Last of the Time Lords" -- Oh, Doctor. (They both lost.)
I'm glad they finally tied up the loose end of Jack getting left behind. All in all, a good end to the season, I think. It was pretty cool to see all the pieces scattered through the various episodes finally fit together.
Also, I would love the Doctor forever just for this line alone: "This is my timey-wimey detector. Goes ding when there's stuff."
