I liked the movie. After all that happened, Marvel still managed to make a entertaining movie.
Paul Rudd and Michael Douglas are great; Michael Peña is so funny.
Unfortunately the villain is weak and predictable.
Screw it, I really enjoyed this movie. Certainly more than Age of Ultron. While I still feel that the film would have been far better with Edgar Wright at the helm, it still really works. Aside from the villain, it was really solid. The action was refreshing in its use of the shrinking powers and ant-sized perspective, aided by great sound work and visuals (there's a certain sound effect that made me a little giddy to hear, I must admit). I wouldn't say it's as good as the Captain America films, but it's definitely on the above average side of Marvel films. And hey, the kid actor isn't annoying, but actually one of the standouts of the film.
And I am certain that was a Spider-Man reference during the ending.
