Okay. So I've seen this post multiple times across multiple blogs and I've refrained from replying. But it bothers me every time and I have the words to explain why now. TL;DR: I think the underdeveloped nature comes from the posts implicitly assuming shared backgrounds.
Specifically, I think the original target audiences for the posts OP mentions are, in order: scholars/academics, and people with chronic pain. (I know the second post, though I'm not completely sure about the first.)
But let's take the first example: Indiana Jones but does grant applications and modern academia stuff. So you have this character who is offered mythical plots, but is self-constrained by the modern scholarly code of ethics. That's boring? You have the clash between the standard lone hero myth and a communal scholarly collaboration. You have a character who is being told (presumably believably!) that they are the chosen one, while buying into the modern bureaucracy and systems that helps ensure responsible, ethical scholarship. You have, at the core, a character who is trying to reconcile two ways of seeing the world. That can be allegorical for many many real life scenarios. Gender roles/personal gender ideals. Balancing being of two cultures. The divide between the expectations of a parent and the desires of a child.
But, this is a post that makes sense and has depth if academic structures are already a part of your life and you've thought at length about the ethical garbage fire that science can quite easily turn into.
The second example: first, it's a power fantasy for people with chronic pain. But it also has pretty obvious allegorical details that stick out to me (personally) like a neon sign.
You have a scenario where the most human connection you can have is with a literal demon, something completely alien, but which provides a lifeline of connection. (The medical system is often extremely hostile to human existence but it often provides the best hope of relief/treatment.)
You have a scenario where the only person who is helping you also profits off your misery (the central tension of for-profit healthcare).
The original post did not make the demon a doctor, but rather a nurse. (Often, sympathetic doctors are also at the mercy of an uncaring system and may not have the specialist knowledge to help with a particular problem and the specialists who do are often hostile/uncaring--putting the helpful demon at an explicitly lower level of power reflects this reality.)
You also have additional layers which connect the demon and their patients/show the demon as a mirror: the demon who decided to just treat patients significantly outperformed all of the other demons trying to do things the normal way (allegory for using accommodations and succeeding rather than trying to do things the "normal" way and struggling). Also, the demon looking at life and reevaluating/finding a path that works for them (a common experience after encountering disability).
This is to me a post/chain of posts that are riffing off the experiences of having chronic pain or illness, and I admit, it might not make sense without context or those particular life experiences.
In conclusion: posts break containment sometimes. Most stories sound stupid if you boil them down to much, but "too much" is likely relative to the amount of shared background you have with the poster.
