Writing and characterization were really enjoyable but I loved the misdirect (a being that is many but one, at war with itself and seeking the Doctor's help as mediator) much more than the reveal (the hive-mind is yet another mwah-ha-ha universe-conquering villain), which hurt my overall opinion of this story. We need to see more sci-fi that's about weird things gone astray and less about cartoonish evil needing countered.

Mediocre leaning towards bad, honestly. The antagonist is just an uninspired “what if this everyday thing was an evil alien” that doesn’t do anything interesting with the premise after the first few minutes. The moral of the story is also so unsubtle and surface level. This all felt pretty purposeless. 

Rise of the Eukaryans is a short, silly story, but wonderfully fun and captures the vibe of the Eleventh Doctors era well. It's just the sort of nonsense this era would have, the sort of adventure that the Doctor would describe in a throw away joke but here it is in all, just pure fun.

It was fine overall just ya know fine

This story is so so stupid, in the best of ways. Complete nonsense, and I loved every minute of it. Jean is a very funny character, and the scene of her yelling at her toaster was hilarious.

A.

A fun story which has put me off bread related items forever. Bonus points for the use of my favourite doctor.
