With these simple words Marvel has restarted their hype engine and completely stolen the Thunder from DC. Honestly, I know the thunder god is one of their characters but this was supposed to be DC's month. No longer fighting Civil War in May, right after Deadpool's momentous winter opening this was supposed to be the sweet spot, but I guess Marvel wasn't in the sugar sharing mood. It also may hilariously be a shot at Joss Whedon, because having a trailer with:iron man, War machine, vision, black widow vs captain America, hawkeye, scarlet witch, winter soldier and adding in the black panther on Tony's side, Antman on Steve's with some awesome fight sequences can be considered an embarrassment of riches, that was honestly enough....
Until it wasn't, I already said this on wordpress but Tony Star screaming "underoos" was the cherry, pineapples and whipped cream on top of my already free awesome sundae. It harkens back to Tony's irreverence, it jokingly talks about Marvel's history as the home for spandex(vs DC's love for cowls and capes), and it allows the wall crawler to show up in a flashy, wacky, cocky, and ridiculous way. This is almost as awesome as Chris Evans pretending to be Loki, pretending to be Captain America. You take a tense scene and toss a fart machine in the middle of it. And it lends itself to such awesome parody, as both the webslinger and the merc with the mouth often do because what is a Spider-man or Deadpool cameo without some existential moment of either seriousness or ridiculousness.
