“The Cat Who Walked through Walls” by Robert Heinlein…
Now Heinlein is usually kind of obnoxiously sexist so having a book that opens with what appears to be an actual female character with not just more personality than a playboy magazine centerfold, but what seems like big dick energy action heroesque swagger felt FRESH. Strong start as you get this hyper competent husband and wife team quiping their way through adventures in the backwoods hillbilly country of Earth’s moon with their pet bonsai tree to stop a nefarious plot with some promised dimensional McGuffin.
Book stalls out in the middle as they end up in like… A swinger commune. They introduce a huge number of characters all at once alongside this whole poly romantic political dynamic and start mulling over the planning stage of what seems like a complicated heist plot. Feels a lot like a sex party version of the Council of Elrond with each of these characters having complex individual dramas they are in the middle of resolving…
Aaaand smash cut. None of those characters mattered. We are with the protagonist, the heist plan failed spectacularly off stage and we are now in his final dying moments where we realized that cool wife / super spy set him up to fail like a chump at this very moment for… reasons? I dunno, Bitches amirite?
First time I ever finished a book and threw it angrily into the nearest wall.
I read a bunch of those books because my roommate was in love with them. It established an idea of a writing flaw in my mind that I called “The Heirachy of Cool”. Basically the guy practically has an established character list of who is the coolest. Whichever character in any given scene is at the top of the hierarchy is mythically awesome. They have their shit together, they are functionally correct in their reasoning, they lead armies, they pull off grand maneuvers, they escape danger whatever…
But anyone below them in the Heirachy turn into complete morons who serve as foils to make the people above them seem more awesome whenever they share page time together. These characters seem to have accute amnesia about stuff that canonically happened very recently (in previous books) so they can complicate things for the hierarchy above, they usually make poor decisions due to crisises of faith in people above them in the hierarchy… But because that hierarchy is infallible it’s predictable. Less cool never is proven right over more cool.
… Until that same character is suddenly alone and they go from being mid of the hierarchy to the top and all of a sudden they have iron wills and super competence…
Once I caught onto that pattern it became intolerable to continue.
