I wouldn't even really call it depressing and dark, tbh. I watched it because someone told me it was "similar to true detective" and I felt kind of like It'd been lied to; the show's mystery was easily predicted, and the cast of characters didn't really have much charisma about them. Not that the acting isn't good or anything - it's just a show about people who suck. Everyone's shit. And sometimes that's a good watch, but I bounced right off of it because of it.
