DC promised that Titans, its live-action adaptation of the Teen Titans comics, would be dark and gritty. And if the trailer that just dropped is any indication, it will be following through on its promise.

Depicting the formation of the Titans team, the trailer starts off with Dick Grayson, also known as Robin and played by Brenton Thwaites, and Raven (Teagan Croft) having a back-and-forth that fuels a dreamlike flashback to the tragic deaths of Grayson's parents.
