Neil Patrick Harris and Yahya Abdul-Mateen II join Keanu Reeves and Carrie-Anne Moss in a fourth instalment in the franchise that is full of little treasuresThis article contains spoilers for The Matrix ResurrectionsThere’s no need for a blue pill. The Matrix Resurrections is, by and large, an engaging and energetic motion picture, and worthy of being on the same shelf as the groundbreaking original from 1999. Unlike the soul-crushingly dull previous entry, The Matrix Revolutions, it remembers that mind-scrambling pseudo-intellectual yammering gets tiresome on-screen if there isn’t also some fun. Luckily, director Lana Wachowski, working apart from her sister Lilly for the first time, and her screenwriting partners David Mitchell and Aleksandar Hemon, have included plenty of flashbacks. A rewatch isn’t absolutely necessary. But talking about the new one after you see it is.
