Grimgrey
The extremely pretentious and poorly-executed cousin of Grimdark, where everyone lives morosely ever after and the creator jerks themselves off with the idea that they made Powerful Art(TM). If a story makes you regret the energy you invested in it, it's likely a Grimgrey-type story, and Grimgrey stories are always failures in that regard.
Grimdark: "Bring all the guns and we might just survive!"
Grimgrey: "They brought all the guns, but they didn't survive. Everybody died and those who didn't were traumatized messes for the rest of their miserable lives. No one was ever happy ever again, now go cry in a corner about existence while I, the author, give myself prostate orgasms with how far my head is up my own ass."
