I liked this episode A LOT better. I liked the new Doctor A LOT better. Maybe it was because I didn't have to be reminded that the tenth Doctor is still the Doctor; he just got a new face and attitude.
10th Doctor really grew into his own this episode. His first real episode. The "Christmas Invasion" was more of a transition episode.
Love to see Cassandra and Face of Boe again. I love continuity.
The special effects weren't bad either. Were they always this good? I don't remember how the old ones were.
