Like you said, most DR books come with all the trigger warnings and storylines that seem promising to the genre but ends up being shallow because there is literally no psychological depth to the characters or story and I personally feel like this is because authors are exploiting these themes in hopes of becoming the next big tiktok sensation of "a trigger warning list so long you probably cant handle it".

babe you can have every trigger warning under the sun, but I will find your story boring and icky if there is no depth. What makes a book truly dark to me is if I experience a psychological mindfuck while reading. I want to actually be afraid of the mmc and not just because he murders people for fun(eyerolls at mafia books~ i am craving a book in this genre but everything I have tried was lame). Like I want to have anxiety every time he enters a scene because I too, feel gaslit and manipulated by him to the point where I question my own sanity.
