The Five Doctors
So I think the biggest problem with this episode is that there's no reason for almost anyone to be here. Troughton, Pertwee, and literally every companion serves no role. They just don't
do anything. The only characters who actually matter here are the First and Fifth Doctors, insofar as they're the only ones that make decisions that set events into motion and solve problems, even if they're pretty easily solved problems.
When I watched The Three Doctors a few weeks ago, my big takeaway from that anniversary story was that while the plot itself was nothing special and the villain was particularly terrible, what made the whole thing worthwhile was Pertwee and Troughton's chemistry together (or rather, anti-chemistry). But you get almost none of that in The Five Doctors. Hurndall and Davison get a few scenes together, but otherwise everyone is kept separate until the very end, which feels like a colossal missed opportunity. It's one thing if you can't actually get five Doctors -- if Baker doesn't want to participate and Hartnell is no longer alive, well, those really can't helped -- but at least make do with the Doctors you do have!
Speaking of missed opportunities: Susan. They replay that clip from the end of The Dalek Invasion of Earth, where Hartnell leaves her behind but promises to come back one day, and here we have the long awaited reunion between the two and...it isn't acknowledged at all. Come on!
On the plus side, I actually thought Hurndall did a fine job as the First Doctor. I've read nothing but almost uniformly negative things about his performance before, and sure he isn't literally Hartnell, but I thought he was a pretty solid imitation all things considered. This was also my first time seeing Peter Davison as the Doctor (aside from the Time Crash short) and while he doesn't get a whole lot to work with, I did like him well enough. It was also nice to see Troughton again, even though for some reason he and Pertwee spend 95 percent of the story trucking around these 30 pound coats.
A multi-Doctor story where the Doctors barely meet; a multi-companion story where the companions don't do anything; and a plot that's heavy on Time Lord nonsense and light on the Doctor doing much of anything consequential. It would've been a pretty disappointing episode if the Rifftrax wasn't so good. I hadn't seen a live Rifftrax in years but they did a great job and really killed on some of their jokes. So when you factor that in, The Five Doctors, while a weak episode on its own merits, averaged out to be a good time overall. And if nothing else, it also gave me a greater appreciation for what Moffat pulled off with The Day of the Doctor.
One of the better Rifftrax live shows. Tons of great jokes.
Think I my favorite was when the Cyberman just walked in the background and then left.
That was my favorite bit too.
