‘Avengers: Endgame,’ the culmination of more than a decade of Marvel Cinematic Universe films, is finally here. We discuss how the long-running arcs of Iron Man, Thor, Captain America, and many others have been strung together and resolved in ‘Endgame.’ Plus, we break down the movie’s complex ideas about time travel, character deaths, and, ultimately, its stakes. Finally, we take stock of where this leaves the MCU, and what could be in store for Phase 4 and beyond.Host: Sean FennesseyGuest: Mallory Rubin
