There's a version of the "don't go grocery shopping while hungry" rule specifically for writers where you should never under any circumstances be allowed to touch your draft within 3 hours of reading a really good story. Because sometimes when you read something great your head goes "fuck this is so much better than my stuff I should make that more like THIS instead!" Look at me. That's the devil talking and you should close the document NOW.
I just finished the Flux storyline and it makes me so upset they introduced this cool idea to us and then IMMEDIATELY took it away again the next episode!! The Doctor turning into a weeping angel would have been such a cool plot point!!
