Geoff Johns doesn't Tweet very often so his post regarding the recently announced Doom Patrol spinoff should be an indication of his excitement for the project.
More interesting is the shoutout to Grant Morrison, who took over the Doom Patrol series in 1989, from issue #19 to #63 in the collected works of Volume 02, Part 02. Perhaps that's an indicator that Morrison's run is an inspiration for the tone and plot of the upcoming series? The book during that period was known for its clever homage and parodies of more famous comic book storylines.
Before Geoff Johns' Twitter feed descended into the utter nonsense of fans demanding the release of the "Snyder-cut" of Justice League, Johns also confirmed the obvious: that the Doom Patrol's appearance in the Titans TV series would be centered on Beast Boy.
