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

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