It's a great story, talking about some important questions, for example the fact that the Curator finds out that he was responsible for the cataclysms in this story.
Fifth Doctor and Jenny here have a great chemistry together, although at some point jokes about "Haha she is his irl daughter" get annoying - and good that they stop exactly when needed to proceed with interesting dialogues.
Colin Baker's Curator is amazing, now being the tired Artist, who tries to hold the art at the end of the universe. If the Doctor ever decides to retire at the end of his life, that's how it should be done.
It's a great story on it's own, but it is almost irrelevant to the overall tory arc. The Doctor immediately forgets everything that happened once he departs and then proceeds to the next story.
But I will lie if I say that I didn't love it. It is irrelevant, yet very enjoyable, heartwarming and just a good listen in general. If you want to listen to only one story from this anthology, pick this one, you won't regret. This one can be forgiven. Unlike the next one...
