<em>Black Adam </em>Is the Nadir of Superhero Movies—And of Dwayne Johnson

I have a couple of bones to pick with the tagline for Black Adam, the Dwayne Johnson–starring comic-book adaptation that sees him swooping around in a lightning-bolt jumpsuit and bringing explosive action wherever he appears. The world needed a hero. It got Black Adam, the film’s poster declares, but if you’ll allow me to quibble, the world actually has plentyof heroes already. Black Adamis barging into the already crowded DC Universe alongside costumed greats including Superman, Wonder Woman, and Batman, and his movie overflows with new ones.
