This thread discusses a story plot point so I suggest reading it before this thread so as to not engage with spoilers.
The story in question is Pact by the talented Wildbow. Point of Order recently reviewed Pact and criticized its use of time magic as a flaw in the writing. In fact, I see it being used brilliantly - which just goes to show that everyone has different tastes. My issue is that I would never put my explanation of why it is brilliant into a review, because it would cause spoilers and ruin the plot for new readers.
So I'm discussing it here. Wildbow describes a demon in-story that erases peoples' memories of anything it eats. This meant that the protagonist saw creatures die but didn't remember bringing any with him to the fight. It created a very suspenseful, somewhat disorienting scene that was brilliantly constructed - and Wildbow filled in the potential plot hole by showing the creatures in a bonus chapter to prove it was brilliantly constructed and not a mistake.
Recently time magic users caused time to go backwards for a mulligan and also induced amnesia, causing a chapter to be skipped. Wildbow is quite cleverly manipulating the conventions of writing to help readers experience the protagonist's perspective - and I applaud him for it.
I challenge Point of Order's perspective that this somehow "breaks" a story or a genre, when it is one of the most creative stories out there. There is no internal logic flaw or plot hole - just some unreliable narration to create reader-protagonist sympathy. It is quite well done.
