A buzz-worthy Transformer outshines an aquatic superhero and super-nanny

On this edition of the Cinema Clash: a superhero origin story that’s bloated but not a total washout, AQUAMAN; a movie musical that doubles as both a sequel and a remake, MARY POPPINS RETURNS; and a ‘Transformers’ origin movie that’s packed with action and heart, BUMBLEBEE. Plus, a fine but forgettable Jennifer Lopez chick flick dramedy, SECOND ACT; a serviceable apocalyptic thriller with a killer cast, BIRD BOX (streaming on Netflix); and an offbeat Korean war drama filled with music, farce, bloodshed and dance, SWING KIDS.
