It was a real let down, after The Christmas Invasion i had high hopes for the series as a whole, but a bad plot, messy acting by David Tennant left me unconvinced, especially after TCI which i thought he did very well. I was really wondering what he was thinking, and i did not feel moved in this plot like did on other episodes like 'Dalek' or 'The Lonely Child' two of the best episodes which left me sad or scared. This plot was a mess. Billie was as wonderful as ever, and seeing Cassandra back was a nice twist. but this better nto set the standard for the whole season, or i am sure Doctor Who will dissappear again. I give this episode a 3 out of 5, and i am being generous, as i was going to give it a 2.
