I know this is probably a common topic. For me, I’m not sure if it’s a “trope” or just totally misinformed writing, but it’s how many authors approach alcoholism. Some examples are Girl on the Train and The House Across the Lake, among HUNDREDS. If anyone else here has struggled with alcoholism, you know it’s not just "i woke up after downing an entire bottle of whiskey but was able to shower, down a cup of coffee, and solve a murder. "
This may not be a trope, but I hate authors that go into a huge description over useless crap. Like describing a person’s bedroom that says nothing about the character to paint a picture of what the room looks like when they never return to the room the entire storyline.
Also, descriptions of city building and architecture. I skip that paragraph 100% of the time.
When I had to read Dickens in high school, our teacher said “Dickens was paid by the word. Therefore, when you come to a long description of how someone looks, or the room they’re in or whatever, you may skip it.”
