The DC Studios co-CEO recently took to Bluesky to explain why The Suicide Squad and Peacemaker Season 1 are not considered canon even though events from both projects are referenced or followed up on in Creature Commandos, which is the first entry in the DCU. "Short answer: Only Creature Commandos forward is pure canon. For instance, Rick Flag Jr was killed because we heard Rick Flag Sr talking about it in Creature Commandos, not because we saw it in The Suicide Squad," Gunn wrote. "Long answer: Only CC forward is pure canon; Peacemaker is almost entirely consistent with that canon other than the Justice League; The Suicide Squad has a lot of consistencies but I think of it as an imperfect memory."
The answer is: we want to try everything and thus nothing should have a real consequence.
While we want to piss out more and more stuff that people pay for we must have the ability to roll back every decision immediately. Someone the audience loved died? It's either not canon or we bring him back from a parallel universe.
What drivel... Reminds me of "somehow palpatine returned"
Long answer for MONEY
