These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ending Fatigue: Pepper Potts goes up against Christian Grey, awesome, right? He gets his ass kicked, bonus!
...Then he decides to sue Clint and Natasha for their ass-kicking, and goes after Jennifer Walters in the process. Okay, cool! Reading about him get beat up by She-Hulk? Totally worth it.
Then he ends up Amora's champion, going after Jane.
And then he organizes a prison riot, and escapes, during which Rogue absorbs his personality and ends up gong after Clint. And that's not even the end of the fic yet, with it running at 68 chapters. Tell me, why haven't they killed him already, again?
Interestingly, the ending fatigue basically is the reason the fanfiction becomes a full-fledged story. While the subsequent sections drag out the initial point of the fanfiction, they're treated more like subsequent episodes.
