what is your favourite and least favourite episode of season 2, and why??

The finale is my yêu thích and least favorite. It's my yêu thích because Rose and the Doctor express their feeling for each other (more hoặc less for the Doctor). It's my least yêu thích for some obvious reasons. If bạn hadn't guessed, I'm a huge Rose/Doctor fan!! So I hated that the Doctor didn't get to say I tình yêu you. I hated the thought that they would never see each other again. :(
