Rising to the challenge of matching its successful predecessor, "Glass Onion: A Knives Out Mystery" maintains the razor-sharp formula, with a setup that feels even more conspicuously like an Agatha Christie homage before an extremely clever series of twists kick in. Writer-director Rian Johnson again assembles a solid cast behind Daniel Craig, but it's his use of language -- where nary a word is wasted -- that finally gives the sequel its edge.
