Now in its 15th year, the Marvel Cinematic Universe that officially began with 2008's Iron Man still seems to be going strong. 2023 marks the beginning of Phase 5 as well, which officially commences with the third Ant-Man movie, titled Ant-Man and the Wasp: Quantumania. While Ant-Man as a character is usually relied on for providing comic relief, Quantumania looks to shake things up by properly introducing Kang the Conquerer, a variant of whom was seen in Loki, and who will be an important overarching villain in the MCU going forward.
The popularity of the Ant-Man movies may be largely thanks to the novelty of seeing characters change size and interact with the world from a new perspective. It's a premise that's been explored in numerous movies released before this latest Ant-Man movie so for anyone who can't get enough science-fiction about people becoming a whole lot smaller than usual, the following fall easy to recommend.
PS - I really enjoyed the new Ant-Man movie.
