I'm once again very impressed with the writer’s ability to explore ideas that they would not dare to in the normal, non-divergent universe.

This one starts well. The Doctor cleverly traps croaker in his mind. We then end up with the Doctor split into three - different representations/ sides of his persona, which is initially very effective. Just before the halfway point though it becomes a comedy runaround which most the time falls flat. It picks back up again when the doctor starts taunting croaker who is doing everything he can to keep the doctor from the TARDIS.

The Doctor is annoyingly flippant in this one. The post-modern noting of all the cliches in the story just made me wonder why so many cliches had been written into the story.

The ending didn't feel rushed as some have said, but didn't feel satisfying either. Regardless - the divergent universe has been an excellent detour and I'm looking forward to seeing what happens next.
