Phase 3C — Ragnarok & The Infinity War (2018)

Phase 3C is the Infinity War proper: the period in which Thanos collects the Infinity Stones, the Avengers fail to stop him, and half of all life in the universe is erased. Avengers: Infinity War (2018) is among the most structurally ambitious films in the franchise — twenty-two characters, three simultaneous storylines, and a villain who wins. Its status as the most genuinely shocking MCU release reflects how effectively the preceding twenty films had established the stakes.

Avengers: Endgame (2019) is the resolution and the farewell to Phase 3's central characters. The five-year time jump, the quantum time heist, the multiverse-spanning final battle, and the deaths of Tony Stark and Natasha Romanoff constitute one of the most complete narrative endings in franchise filmmaking. Spider-Man: Far From Home functions as an epilogue — both to Endgame and to the Infinity Saga — examining what the world looks like for survivors in the immediate aftermath. Phase 3C rewards every hour of viewing that preceded it.
