Serviceable, though junky, superhero fare from DC, still trying to find a steady groove in its cinematic universe. Starring Dwayne Johnson as the antiheroic counterpoint to the far better-natured Shazam fella (you can tell, because Johnson's super-enhanced body is covered in a beat-up looking black costume, complete with a ratty, hooded cloak), "Black Adam" more or less plays the hits you would most likely expect, amid extended bouts of exposition, several quips (some amusing; some not), lots of CGI battles, and Johnson's money-making half-smirk.
