Like most people whose posts I've read, I enjoyed part 2 much more than part 1. In particular, it did a decent job of filling in quite why the Master was so insane, and I also liked the revisiting of companions prior to the regeneration - indulgent but allowably so (and yay! Sarah Jane Smith again), and a bit different from some of the previous regeneration sequences. Wilf was, of course, marvellous, and even better in Confidential where he was shooting away to the music of The Dam Busters. Yes, lots of it was derivative (especially with respect to Star Wars), and I don't think RTD made particularly good use of his "cast of thousands", but what would you expect? It certainly wasn't his worst effort.
