The main criticism for I have for Dostoevsky is that he's overdramatic. Yes it's great fun fiction and a vast improvement over the simpler, more idealized writing of much of his era, but some of the angst of his characters is simply cultural. He has a lot of religious influence in his work (which don't appeal to me as an atheist) and their struggles for the human soul is a symptom of his time. A Buddhist might say, just calm the fuck down man. Most people don't react to horrible situations by "crashing out", but via coping and rationalization and making the best of their situation, that's how you get consistent improvement and accrue generational uplift.
Later writers like Virginia Woolf is able to better integrate a variety of responses to suffering, post modernists like Tao Lin even gets overly detached (everyone hates post modernists). But I think the best novel about the human condition ever written, which handles the drama, but realistically, is probably by Elena Ferrante in 2011. I'm not highlighting any underrated work here lol, it's widely acclaimed, including called the best book of the 21st century by the NYT.
