31x05a Meanwhile in the TARDIS
This two-parter is excellent -- a big proper blockbuster slapbang in the middle of a season of TV! Marvellous! My thoughts from the broadcast all still count, so read them at the above links.
As for this second (and, for now, final) instalment of Meanwhile in the TARDIS... it's non-essential, obviously, but the bit with Amy finding out about previous companions is quite fun. As a fan I'd naturally have liked more time on that aspect of the scene, but hey-ho. Defining the Doctor as "Space Gandalf" is a nice line though.
1x06 Episode 6 [season finale]
After that ending, I'm very glad it'll be back.
