I was pretty disappointed with the episode. Especially since I was a Beatles fan, and the episode itself was marketed as a Beatles episode. But really it was just a sequel to "The Giggle" with John and Paul being the only Beatles that are really featured (I don't dislike the two, but I really wanted to see some George and Ringo action for the episode).

It definitely should've been something like "Vincent and the Doctor" or "The Shakespeare Code", where the historical figures featured actually take part in the story instead of pretty much doing nothing for 40 minutes then just appearing in the climax to play a chord.

Even though I was disappointed with the lack of Beatles in it, I wouldn't say that I hate it entirely. Most of the redeeming factors for me would go to Jinx Monsoon's performance as Maestro and the neat reference to Pyramids of Mars. So I probably would say that it's like "Rings of Akhaten", where the story isn't great, but there's that one bit that overshadows the entire episode and kept it from being a terrible one. That one scene (for me personally) being the Beatles dog song the Pyramids of Mars reference.
