Neat episode, not sure if I like Donna's character, she's a bit cocky for me, (whoa that felt weird to type) I mean, she's likable enough, but Catherine Tate steals the action from David Tennant, (the Doctor) who should be getting the attention. Casting Tate wasn't a good idea I don't think. Piper and Agyeman, Tennant's previous companions, were relatively unknown actresses when they took on Doctor Who. People would sit down and watch them, and say, "Who's she?", where's with Tate, everyone knows her.
