Now this is a story I really enjoyed.

I'm a big fan of Arthurian legend, so this, bringing characters from legend into the present, dealing with the repercussions of events from years back, and then also introducing new characters in the modern day, a half-dead hacker who tries to cultivate an aura of mystique but in reality being a ray of sunshine, it's just a really fun story.

I really like how the flashback sequences are interspersed with the main story, and some of the descriptions of the monster are really interesting. The way it's defeated as well I think is a really fun twist and makes it all the more unique, it also ties in thematically to the ideas of myth and legend that the story's already playing with, which is another thing that just makes it work.

I also really enjoyed the epilogue, using The Doctor while legally not doing in that way is just a lot of fun, and I think the characterisation here is pretty interesting!
