david copperfield, for example, is an incredibly dull read (imo). but it doesn't actively bother me having read it, and sometimes knowing how it goes comes in handy. so overall i don't care about it but i'm situationally glad i read it
the wizard knight, by contrast, combined poor writing quality with stuff i found highly disturbing in a way that means i can't entirely get it out of my head. literally just the knowledge that i read it is stressful. i regret having read this book
this pretty much delineates the three categories:
• bad books i'm glad i read, it's because i learned from them
• bad books i regret reading, it's because something about them is actively stressful—disturbing (or actively triggering) content or exceptionally poor basic writing skill, for me
• bad books i don't care about are mostly just not compelling. nothing especially hateful beyond a lack of especially positive qualities
i will, however, encourage folx to look into dickens' work if you're not already familiar with it. i wouldn't generally recommend any of his novels, but his short stories tend to be good and it's worth reading commentaries on a christmas carol just for the history—i'm legitimately impressed by the amount of detail he fit into that one story in support of better treatment for the poor, and a lot of it is hard for a modern audience to pick up on. so decent commentary contextualises a Lot of things
correction: it's exceedingly common for them to be really d__n disturbing for a modern minority audience
from my understanding, most cis white dudes are left unscathed by reading these
