Controversial opinion: I enjoyed Black Adam.
JSA vs Black Adam remains one of my favorite brawls in superhero films. A lot of fun uses of powers while respecting the source material where they came from.
I enjoyed Dwayne Johnson's dedication to the role and character. He got so unbelievably ripped for this role despite his age, it was cool to see. And yes, I enjoyed his portrayal.
There were problems for sure. Skateboard kid was a bit much, the supporting characters were a bit tropey, and the villain could have had a better motivation.
But IMO, the pros greatly outweighed the negatives. A shame we will never see a sequel.
