It’s the first Avengers movie, the next Iron Man movie, the next Hulk movie, the next Thor movie, the next Captain America movie, and the first S.H.I.E.L.D. movie, all at the same time. It’s the jewel in the crown of the MCU, tying together lots of threads and also being brilliant on its own. The great superhero movie rewatch gushes over Avengers.
And in fact, this movie is full of great lines. One of Whedon’s hallmarks has been his snappy dialogue, and this movie is crackling with it. I could use up my entire allotted word count on this rewatch just quoting lines from it, which I won’t do, but I will in particular sing the praises of all the callbacks, whether it’s the ant-boot conversations between Fury and Loki, the payoff of Fury’s “ten bucks says you’re wrong” line to Rogers when the latter says nothing can surprise him anymore, the constant exhortations of Rogers to Stark to “put on the suit,” going from macho posturing to an instruction to help save the helicarrier, or my favorite: early on, Pepper Potts refers to Coulson as Phil, and Stark jokes, “‘Phil’? His first name is ‘Agent’”; then, later in the movie, when as Iron Man he confronts Loki, he mentions the final person Loki has pissed off: “His name is Phil.”
