An enjoyable episode but nothing groundbreaking. I think the "small English town with a superstitious old witch and a cult that are secretly worshipping what is actually an alien" trope was done better in The Dæmons, and at least that one had a fun villain.

I like the design of the Fendahl - I almost want to cosplay her - and Fendahleens, even if it was very similar to the design of the Drashigs.

Leela's new dress didn't fit her properly at all, and the bun wasn't a great look either. I'm glad they seemed to reset back to her old look at the end.

As is the nature of any long-running show, there were plenty of things I felt other episode of Doctor Who had done both better and worse than this one. Nothing is truly original, but it's amazing to see the same plots and tropes repeat on the same show to such varied results.
