I haven't finished the book, but I have to give it to the "Navidson record" in "House of leaves".
House of leaves is a book about a guy who finds a manuscript about a movie that doesn't exist. So there are multiple layers on the narrative, from near to far you have:
- The editor who's editing the book
- The writer of the book (Johnny) who tells his story and what he finds in the manuscript
- The person who wrote the manuscript (Zampano) and his views on the movie
- The documentary "The Navidson record" which the manuscript is describing. Filmed by Navidson (who's, as far as Johnny can tell, a fictional character in a fictional movie that never existed)
The reason why I have to give it to that particular piece of media within media is that everyone else in the book is a pain in the ass that feels that you have to drag yourself to in order to get to the next chapter of the Navidson record. So in a way it's a fictional media within a fictional media that's better than the fictional media it belongs to.
And in case you haven't heard of house of leaves, I'll leave you with a page from the book:
