It was a really nice more down to earth cape flick. The cheesy lines from the trailers about how Ant-Man sounds stupid weren't even in the movie. Definitely one fo the most enjoyable out of the bunch, in the same category as first Iron Man and Winter Soldier.
People who legitimately thought it was going to flop severely underestimate the hype of Marvel movies. Even normies are suspicious of WB after GL and DKR, Man of Steel got mixed reviews, but people were less hype for it than fucking Guardians Of The Galaxy - which were mostly completely unknown to casuals.
What I think is interesting is that in the rest of the world Ant-Man is the third least in-bringing MCU movie, but the Chinese loved it; it's only beaten by Avengers in the box office. Why is that? Is it the Kamen-Rider/Super Sentai-esque suit?
Or do Chinese just really love ANTS?
