Black Adam was supposed to change the hierarchy of the DC Universe. Instead, it tanked with critics and couldn't conjure enough magic at the box office to earn a sequel.
Thus, it appears the Rock's long awaited appearance as the anti-hero is a one and done. Frankly, that kind of sucks because Black Adam is an entertaining movie. It's a flawed one, to be sure, but watching the titular hero mow down bad guys is a hell of a lot of fun.
Throw in an exceptional Pierce Brosnan portrayal of Dr. Fate, as well as a more than capable Hawkman adaptation (played by Aldis Hodge), and the groundwork for a bigger, better sequel was laid.
Alas, it is not meant to be. Grossing just $392.6 million on a budget north of $200 million, Black Adam couldn't prove its worth to the new DC higher ups. Bummer.
