Marvel Studios folds together characters from just about every comic book franchise it's got for one giant-sized, free-for-all brawl. When power-mad alien conquerer Thanos (Josh Brolin) tries to unite the six Infinity Gems, The Avengers, Black Panther, Doctor Strange, Spider-Man and the Guardians of the Galaxy must join forces to stop him from using them to wipe out half the life in the universe. Anything you can say about this counts as a spoiler. It's certainly not the best entry point for the Marvel Cinematic, relying on 10 years of backstory and setup. But it is a surprising, satisfying and shockingly dark capper to this second phase of the MCU.149 minutes PG-13.
