I’m happy to see a ship in the bottle episode in the TARDIS. Last season’s Doctor’s Wife was more psychological while this was more action oriented I thought. It is the one type of episode that could easily be stretched out into a multiple episodes and I wouldn’t bat an eye since Doctor Who has been around for 50 years and after 900 years the Doctor must have an metric ton worth of baggage and possibly even a stowaway civilization on board.
The set designers pull off some nice rooms: the observatory, the aforementioned pool, the library, a giant tree that can manufacture anything you want and the TARDIS’s engine room which impressed me more than her center.
Unfortunately, it’s the leaps in logic that’s making me re-watch the last five minutes and I’m starting to agree with my mother: Is this half of the season sucking.
