I like Ant-Man. He’s literally down to earth — after the intergalactic super-villain Thanos plotting the wiping out of half the universe, it’s nice to see our hero up against an ordinary, non-super thug of a bad guy. And it’s also nice to see, 20 movies in, a female superhero in the title of the film. I like the slightly retro, slightly bookish look of the Ant-Man films (outstanding work from production designer Shepherd Frankel). And I like the fun they have with scale. Scott Lang (Paul Rudd) can do more than shrink himself to the size of an ant and call on his ant friends to help him out. He can make himself and objects around him get bigger or smaller almost instantly. And the Wasp (Evangeline Lilly) can do all of that AND fly and use her wrist blasters.

Scott has three more days to go under house arrest, wearing an ankle bracelet, with frequent check-ins by the local authorities, led by Jimmy Woo (Randall Park), who can’t seem to decide whether he wants to lock Scott up or become his BFF. He’s going a little stir-crazy, though he enjoys the elaborate games he creates for his daughter, Cassie (Abby Ryder Fortson). The terms of his parole forbid him from having contact with Hank Pym (Michael Douglas) or his daughter Hope (Lilly), but that has not been a problem. They are not speaking to him after they think he betrayed them by making their technology public in “Captain America: Civil War.”

But something else that happened in “Civil War” is the reason they have to find him again. Pym’s wife and Hope’s mother, the brilliant scientist Janet Pym (Michelle Pfeiffer), became too small and they thought she was lost forever in the “quantum entanglement.” Scott was able to return from the quantum entanglement, though, and they want to find out how and send him back there to see if Janet can be rescued. This is a job for two superheroes, and so it’s time for Hope to suit up.

An all-around crime boss named Sonny Burch (Walt Goggins) wants to stop them from getting the material they need to make that work. A character whose backstory I won’t spoil but who can vibrate through matter also wants it. And the cops are trying to capture the Pyms as well. So, lots of chases, lots of hand-offs and near misses. Director Peyton Reed and his writers (including Rudd) have a lot of fun with scale, sizing the vehicles up and down in an instant and Scott himself getting as big as the Statue of Liberty (which is exhausting for him) and as tiny as an atom. His suit does not always work correctly, though, and his judgment does not always work correctly, either.

The distinctive humor of the first film continues in this one, with Michael Pena returning as Scott’s loquacious fellow ex-con and business partner. His circuitous story-telling was funny in the first film, and it gets funnier here when he is questioned under the effects of what could be a truth serum (whether it is or not is a point of contention). Random topics that also come up for discussion include close-up magic, the Slavic folklore character Baba Yaga, loading the dishwasher, and playing the drums. There are some great action sequences, especially one in a kitchen and the chase scenes, and crisp pacing to balance the more laid-back comedy. Its biggest failing is the dumb nicknames for the daughters of the characters. Really, Peanut? Jellybean? Those girls deserve something as witty and distinctive as the rest of the film.

NOTE: Stay through the credits for a brief update on the “Infinity War” cliffhanger, and then all the way to the end for an even briefer and very silly little second extra that has an important clue.

Parents should know that this film includes extended comic book/action peril and violence, characters injured and killed, some scary images, mild language, and some parent-child issues.

Family discussion: What changes do you think the quantum experience has on people who travel there? How is Ant-Man different from the other Avengers?
