Witty, nimble, sharply dressed, and light on its feet, Guy Ritchie’s dexterous “The Gentlemen” is a largely surprising delight (mostly, anyhow)—an entertaining crime comedy with a snap, crackle, and pop that’s far superior to the more self-enamored 2019 film of the same name whence it came. The connections to the original are tenuous at best, nothing more than the cannabis and drug empires milieus in the U.K.
