Yes, there is an oversaturation of superhero movies, but Marvel's Ant-Man and the Wasp, the sequel to 2015's Ant-Man, is great fun and one you shouldn't miss in 3-D. This is a sequel that is just as good as—or maybe a little better than—the original.
Doing a synopsis for this one is a nightmare because there is a lot going on. So, master thief Scott Lang (Paul Rudd), now under house arrest, has no choice but to don, once again, the super suit that allows him to shrink and enlarge as well as communicate with ants. The creator of the suit, Dr. Hank Pym (Michael Douglas), needs Scott's help. You see, Pym thinks his long-dead wife, Janet (Michelle Pheiffer), may actually still be alive, but trapped in a place called the Quantum Realm, and he needs a certain device to get to her and to take her home. Pym's daughter, Hope (Evangeline Lilly), also has a super suit and calls herself The Wasp. Together, these heroes battle various villains, including Ghost (Hannah John-Kamen).
Admittedly, there are some story holes you may want to ignore, like how it doesn't make sense that no onlookers notice a building appearing then disappearing from a vacant lot or see a scientist shrinking and enlarging cars. Only later in the picture do pedestrians begin to notice these things.
More memorable is the grand set piece of the movie: a wild car chase finale with miniaturizing vehicles, a giant-sized Ant-Man, and even an enlarged Pez dispenser. It's crazy and exuberant and just what the summer ordered.
Parents be warned: There is a cliffhanger sequence midway through the end credits, tying this movie to Avengers: Infinity War, that may upset younger children.
