Burnt circuit in the brain

Nicole Kidman's character Erin Bell is an utterly joyless person. A lacklustre, dull and grey person. A humourless git. She'd be an abomination to hang out with. She tries to be a decent mother though, but she's too detached from work. She's an undercover agent with a vengeance in mind. Destroyer is a crime drama with such a melancholic theme that it's inescapably boring.
