Matt Smith's Doctor, Jo Grant, and a whole bunch of references to the other companions! Great episode. And nice to hear the Unit Rocks theme again

The plot doesn’t add up to much but my word it’s made up for by the character moments. It’s the Tales of the TARDIS before it’s time. Jo Grant meets Sarah Jane. Clyde meets the 11th Doctor. As a fan it is mind boggling to see these four characters share scenes as they are meant to inhabit different hemispheres of your brain. Russell does a really lovely job.

The Shansheeth are a delightful creation. Perfect puppets! And this headbands - very classic. And the clips of the old show. It’s a feast of treats.

It feels like a bit of a last hurrah. They’d never get to operate at this level of fandom-ness ever again.
