Trying to find a recent post

Sometime in the last month or so, someone wrote a post commenting about the "The Flash" movie not being the movie they wished it was (or something like that?) and then either linking to or including a fanfic about time travel and the things that require a villain rather than a hero to save the world.

I want to share it with someone, and I haven't been able to find it. Does anyone else remember and have a pointer?
