Quite a good story, though slightly undermined by it's constant cutting between locales. On the one side, a strange disappearance in Amsterdam; on the other, political machinations and treachery on Gallifrey, with the latter being a far stronger story. I was quite compelled by the cast of shady Time Lords and their ulterior motives, though the design of Gallifrey was a little underwhelming, and the pacing was rather slow. On the upside, though, we had Nyssa with a gun, Colin Baker's Maxil, and Omega's jolly holiday in Amsterdam, complete with some quite splendid shots of the TARDIS team pursing him. And naturally, we had the triumphant return of Tegan Jovanka. What more could anyone ask for?
