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

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