Very nice review, Miss Diva. I was drawn to the series because Ben Kingsley is in it. He was good, and carried many of his scenes, but the writing should have been better. I hadn't known anything about the Wonder Man superhero, so I presumed the story was tongue in cheek or a send up (like Birdman).
It took until Williams had an anger/shock wave episode that I realized he had super powers. But you're right, the script needed to show him displaying his powers more in order to drive that aspect home. Plus, a guy who actually had superpowers looking to get hired to play Wonder Man is a bit much. I also think that Abdul-Mateen was miscast. I didn't believe him in the role.
