This episode has everything that makes a Doctor Who episode amazing. It is full of emotion particularly toward the end, it sets up very powerful character confrontations, has a very deadly threat for The Doctor to deal with and some heroic scenes from Tennant accompanied by Murray Gold's score, which is yet again masterful. What starts off as a casual adventure ends up being one of the most powerful stories for The Doctor, with a chilling ending.
