Okay, well I was in two-minds about this, so perhaps I had better divide this into two blocks. What I liked and what I didn't about the last two episodes.
The use of previous companions, although I will keep on saying this "Please bring back Brigadier Lethbridge-Stewart"
The return of Davros, who was brilliantly played by Julian Bleach and was still on form
The ending. So sad, worse than what happened to Jamie and Zoe, and yet relief that no one got killed
The use of Torchwood
The cliffhanger at the end of The Stolen Earth? How can you beat that!
The added menace to the Daleks. You can no longer impair their vision and they can see!
The trampling over, although thankfully not completely, the previous assertion that the Doctor is half-human. That explained so much and was the best thing about the TV Movie
The towing of the Earth back to where it belonged
The fact that Mickey could just calmly walk out of Rose's life after all they went through!
The "Mexican stand-off" the companions had with the Daleks. Good idea, but a bit overdone
Too many companions. This would not have been a problem had they panned out the story a bit more!
And thats basically it, but am looking forward to Season Five in 2010 and the specials in-between. Esp with Steven Moffat soon to be at the helm. As for favourite stories this season there were so many, but I did esp like The Fires Of Pompeii, Planet Of The Ood, The Doctor's Daughter, Silence In The Library/ Forest Of The Dead, The Stolen Earth/Journey's End
Oh and doesn't Davros remind you oh so slightly of the Emperor in the Star Wars films?
