There are certain plots and tropes that I'm so tired of seeing that if I come across a story with them, there's a high chance it's a boring cliche story that I'm going to dislike, even if I'm otherwise good with the level of weight gain and kinks
- Anything to do with the bully cheerleader/athlete brought "low" by weight gain. This story has been written 1000 times and your take is not going to be any more original. Bonus negative points if its set in high school or references Mean Girls
- Similarly, most stories with models gaining weight are boring and just have the character go from super model to obese without much fanfare or exploration
- College set works better be damn original or interesting to read. Congratulations on discovering the concept of the Freshman Fifteen, you're not being clever when you turn it into the "Freshman 150". I'm fine with a character having gained a realistic amount of weight in college as a background detail, but don't make it your whole story unless you're a really good writer
- Any story where a guy secretly fattens up his girlfriend and she is instantly fine with it and has minimal or no conflict or turmoil, even more so if it's never revealed and the story just ends with "my girlfriend is 400 pounds and a huge lazy slob and happy"
- This is a newer one that's only beginning to be old hat, but stories about streamers getting fat. I actually do like this setup but I'm seeing so many works that just absolutely do nothing unique or interesting with this, just "what if a streamer snacked a lot and got fatter with each stream"
Again none of these (well except the first IMHO, that was becoming tired in the early 2000s) are damning and can be done well with quality writing, decent characterization and/or interesting twists. But considering so much wg fiction out there lacks all three of those, the above have become my bad story smells.
