Definitely a solid story with an interesting premise and plenty of fun character moments. Unfortunately, there are many  tropes in this serial which I feel were done better in previous episodes of the show.

Romana is much more enjoyable in this episode than the last, actually feeling like a proper character for the most part. I like how much she seems to enjoy the Doctor's antics.

I found the Captain a bit too over-the-top and poorly acted to enjoy, and his quick 180 when Mr. Fibuli died felt very unrealistic with his previous characterisation.

I felt that the story forgot the overarching plot of the season a bit too much. It didn't feel like the Doctor and Romana were at all focused on finding the Key. One thing the previous episode did better was integrate that into the plot.
