I wanna break my rating down more. 

This is a book inside of a book about a movie. So at the core we have the book Z wrote, which is an analysis of a film that was released in the 90s of a man explore his house once he realized the house is bigger on the inside then the outside. But more accurately it has a closet that is an impenetrable labyrinth of cold darkness. Then JT finds Z's book and decided to finish it for him, while insert his own tidbits. Then we have the professional editor clean it all up, and being the same voice through it.

With that in mind:

Navidson Storyline - 5⭐, I enjoyed learning about the house and the way it affected those exploring/experiencing it.

Z's analysis - 3⭐, some parts felt pointless and some felt like they did add to my understanding of N. Recods.

JT's shit... 2⭐, I fcking hated reading through his monologues. While sometimes it was interesting to see his journey into madness and how it relates to Z's... Like 80% of his rumbles just felt like some guy with low self esteem that didn't know when to stop talking.

The editor aspect feels like a 4⭐, they just felt like comical relief(they weren't funny so more like sane relief), but from the insanity your wading through.

Which to me feels like it averages out to a 3⭐ overall. Doesn't help that I just read You Should Have Left by Daniel Kehlmann, and that book felt how I wanted JT parts to feel.
