While I liked Space Babies more than I expected to, I actually liked this slightly less than I expected to, that said it is still the better episode of the two. Maestro was fantastic. I'm not sure they always stayed the right side of OTT but in the end it didn't matter.
I was worried at the end that the Doctor was going to beat Maestro, then I was worried it was just going to be John before Paul showed up but the two of them together defeating Maestro was fab. I have to say though, given they were in the episode so little could they really not have found actors who better looked like the Beatles? I was reserving judgement until the episode but they weren't even close. Maybe they didn't make much effort because they knew they weren't going to be in it?
I was a bit annoyed that the Doctor went from Terrified and convinced he couldn't beat Maestro to going toe to toe with them in the musical battle. I don't have an issue with the more fantastical theme of this era, and heck the Doctor has fought Gods before (heck I wonder if even Fenric was a child of the Toy-maker?) but in the same way you can overdo technobabble, I don't want to see every villain dispensed by cheap tricks or using just the right sequence of words, it can get old real fast.
The lack of Beatles music was very noticeable and I'm still not 100% sure about the Austin Powers dance at the end, again I hope this isn't a regular occurrence.
Some interesting Easter eggs, apologies if people already know this.
Murray Gold is playing the piano onscreen during the final song.
That little old lady was only
June Freaking Hudson! Costume designer on Dr Who, Blakes 7 etc.
Jeremy Limb, who played the composer killed by Maestro at the start, is the son of Roger Limb who was part of the radiophonic workshop and who scored Keeper of Traken and a bunch of Davison stories.
And finally,
is this the most obscure An Unearthly Child link possible?
