The Venture Bros.' cancelation is like ending the MCU before Avengers: Endgame

"It took DC Comics and Marvel Comics decades to build out the complex, interconnected, self-referential universes that they eventually mined for their movie projects," says John Maher. "It took The Venture Bros. creators Doc Hammer and Jackson Publick three seasons to create a similarly rich world crammed with heroes and villains. And then, in the season 6 premiere, they did it again, in the equivalent of one of DC’s timeline-resetting crisis storylines. At the end of season 7, the showrunners finally played the hand they’d been holding since the beginning: the eponymous Venture Bros. were not who they seemed to be. The Venture universe was just about to enter its biggest spin yet. And then, with little more than a couple of tweets, the show was abruptly finished, like a world erased by the Anti-Monitor, or eaten by Galactus. Except Hammer and Publick didn’t get to write the ending."
