Some of the most fun Delgado gets to have all season, and that's saying something given he's in everything.

Generally just a really fun vibe for this story, putting the doctor more on his own for most of it with the Brig and UNIT reinforcements trapped outside, aliens that inspired myths are always fun, and I love the contrast between the dark underbelly of cults and magic run by the master vs the quaint little village over on top, especially when the latter gets to influence the former as the story progresses.

If I didn't love Bessie before I absolutely would now, this story cements her as a brilliant part of the UNIT family, I especially love The Master trying to get away in her and then being slowly driven back.

The effects also surprised me, Azul isn't the greatest effects-wise, but he's not too bad either, and UNIT showing off the heat barrier was some great practical effects.

All in all just a brilliant story!
