18. Galaxy 4

Galaxy 4 kicked of Doctor Who's third season. Unfortunately for many years, all footage was lost until last year when one episode was finally found. That episode is to be released in March at that point, I shall write a review.

UPDATE 3/20/13
Released with a special edition of The Aztecs, the newly discovered 3rd episode of Galaxy 4 is an extra special extra feature. Nestled within a telesnap reconstruction of the story with the original soundtrack, the episode is a highlight of the piece. It really is a joy to see a NEW episode of LOST Doctor Who. From the extant surviving material, the story presents an interesting gender play and a parable on don't judge a book by its cover. I probably would not have chosen this story to launch the season but with the Dalek Masterplan a few stories away, it was a quieter beginning to a monumental season of Doctor Who.
