TL;DR – While individual elements work, when you combine them with a story that feels kitbashed together from other/better narratives, you get a bit of a disappointment.

Ant-Man and the Wasp: Quantumania Review –
Sigh … okay, let’s do this. I feel before I go on that, somehow, I need to build a touch of credibility on the topic of Ant-Man. I don’t know why, but let’s just go with it. I unashamedly love Ant-Man, as well as, Ant-Man and the Wasp. The first Ant-Man was a perfect coda to Phase 2, a surprisingly fun romp through San Francisco and size. The second was a breath of fresh air in-between the dourness that was the two Avengers. I loved that we were getting a third, but something in the marketing campaign made me pause … I think I should have listened to that part of myself.
So to set the scene, after helping to save the world in Avengers Endgame, Scott Lang (Paul Rudd) has tried to be a better father to Cassie (Kathryn Newton) who he has years of catching up to do, and a better boyfriend to Hope (Evangeline Lilly). All while writing a best-selling book. However, that ball of calm is crushed when Cassie is arrested at a protest, and her grandparents Hank (Michael Douglas) and Janet (Michelle Pfeiffer) might have been supporting her more rebellious side. But it is Cassie’s work in trying to chart the Quantum Realm that brings everything unstuck. Because as they knock at the door of the realm, something knocks back and sucks them all in. Now it is time for Janet’s past to catch up to her in the future.
