Haven't seen Antman, son liked it. Son talked me into Kingsman (didn't have high expectations). Having seen Kingsman, there is nooooo way that Antman is better (i.e. I liked it a lot).
Well, I liked Ant-Man better than Avengers: Age of Ultron because Age of Ultron didn't have any heart to it. And Ant-Man did. Because you see, Ant-Man was about fathers and daughters.
