Dwayne "The Rock" Johnson is back in the home theatre, this time in what appears to be at least partly a vanity project that brings some of the more obscure DC Comics characters to the forefront.
Black Adam, not to be confused with Black Adder (God forbid!), is a "super anti-hero", a God-like being from ancient history who's awakened in our modern day and called upon to defend his descendant countryfolk from whatever band of robbers and thugs happens to be running the show there at the time.
"There" is Khandaq, which appears to be somewhere in the Middle East. It isn't a secret place like the Marvel universe's Wakanda, but it does appear to be a tad off the beaten track. This means, at least according to some of its residents, that it's been prime for exploitation by bad folks, while also ignored by DC's usual gang of superheroes that includes such folks as Superman, Batman, and the like. No Justice League member has ever come to rescue the put upon Khandaqians (or whatever you'd call them).
An old Fawcett character from the Shazam books. Not really interesting and certainly not a vechicle for Johnsons venture into the superhero genre. Slightly below the live action Scooby Doo and a notch above Turkish Batman. This is prime MST3K stuff.
