The story of Ant-Man follows Scott Lang(Paul Rudd): a former ex-con trying to redeem himself for his past crimes. When things do not go according to plan, Scott decides to return to a life of stealing. However the house he robs belongs to retired scientist Hank Pym (Michael Douglas). Scott steals is an odd looking suit which he discovers has the ability to shrink the wearer in size. Scott finds out that Hank Pym was once a hero named Ant-Man; and Hank has been watching Lang so he can take up Pym's mantle. With the help of Hank's daughter Hope (Evangeline Lilly) and Scott's Crew (Michael Pena, Tip T.I Harris and David Dastmalchian), Scott becomes the Ant-Man and must steal from Darren Cross (Corey Stoll) who is bent on using Hank's formula as a weapon.
Ant-Man was a fun little superhero film (and that pun was intended). The story and characters, while not perfect, still fit both the concept as well as the title of Ant-Man. Plus the effects made the movie feel larger then life. Ant-Man may not be Marvel's biggest film, but this blockbuster was both a fun summer film, and it definitely belongs in the Marvel Cinematic Universe.
