I remember reading a harry potter fanfic series somewhere in 2010-2012(roughly) that narrates through the movies, and basically makes fun of it. It was posted on fanfiction.net though I'm not able to find it on searching for it there recently.
There were multiple fics done, each based on a movie up until the 4th or 5th movie iirc. The author makes fun of multiple movie decisions like mary-sueing Hermione, making Ron a bufoon etc. It also makes fun of Steve Kloves multiple times.
The format was like a script book so it would be like:
(scene description in brackets)
Harry: blah blah blah
Hermione: reply blah blah
(funny comment by author/narrator in brackets)
I remember in the fic based on third movie where the actor who played Dumbledore changes, there was a funny reaction when new-Dumbledore appears and everybody is confused about who this guy is.
