I absolutely love this episode because it's so fun and adventuresome, while it does a great job of introducing and defining Martha. In general, I think RTD is absolutely fantastic at creating new characters, giving them a life and history, and then introducing them and defining them for us - by the end of the "Rose", "The Christmas Invasion", "Smith and Jones", and "The Runaway Bride", you already pretty much know who these new characters are.

I actually really miss the surreal quality that RTD's episodes have - from the hospital on the moon thing here, to the situation and the people in "Gridlock", to even the rather anachronistic people in "The Fires of Pompeii" (the Caecilius family being so modern-normal and the Cockney street vendor). The classic show and the BF audios sometimes have the same quality, and it draws me to them more than does the current show, which, to me, feels much more standard sci-fi.
