A really fun and enjoyable story! So good to see Troughton again, and his chemistry with Pertwee is an absolute delight to witness! I wish I could enjoy Hartnell's bits, too, but it was actually more heartbreaking to watch than anything else. Still, I'm glad we got these last few appearances of him before he passed on.
The actual story is quite simple and not the most complex, but it doesn't need to be; the main focus of this story, really, is seeing the multiple Doctors work together, and what a treat it is. I really enjoyed Pertwee and Troughton together. I wish it were longer! Four parts really didn't feel like enough.
My only gripe would be that Omega's voice was unexpectedly off-putting... It just didn't sound right.
He reminded me of Gulliver from 'The Mind Robber'. Throughout all of Omega's scenes, all I could imagine was Gulliver under that helmet. It should have been a deep and angry voice. However, Omega was still a very interesting character and it's great to learn more about the Time Lords' history and how they discovered time travel. Certainly an enjoyable villain.
Great story and highly recommended, for Troughton and Pertwee if nothing else!
4/5
