I enjoyed it! I must say I was surprised by it, I went in not knowing what to expect by that title, but I must say it’s pretty good, actually. It’s not a masterpiece by any mean but from the early plays I listened from BF they did have some struggle to remain memorable in my head, for example it’s been longer since I listened to Dust Breeding, but I can’t remember much of it, besides the aspects I liked, this one on the other hand? Memorable for sure! The Idea is one that I am surprised wasn’t done much before (referring to the Idea of a “Fraud Doctor”) and the Comedy in this story really gives Colin a lot to work with in his Performance. In many way this feels like a much better Execution of the Core Idea of the Next Doctor, even if both differ from each other with having one being aware of being not the real thing and the other doesnt.
Overall, I enjoyed it!
