I did enjoy this episode. I watched it on the Season 20 Box Set, with the original CGI. It's a quick four-parter that I find builds on Gallifreyan lore, even if they don't have the strange headresses. Overall, the return of Omega (Played by Ian Collier) is a nice link back to the 10th season, which was also an anniversary story. I'd personally have preferred they spend more time on Gallifrey, but I understand that there's not much to do on that planet. Peter Davison did a good job in a dual role, and I would've been surprised at Tegan's return if I watched it live. I also enjoyed the setting of Amsterdam, since it's a place the show doesn't normally go. Still, I enjoyed the mention of Leela. Nice to see she's happily married. For now, anyways...
