The problem might be Temuera Morrison
I have nothing against Temuera Morrison. He seems like an ok guy.
But one of the reasons the show is not doing that well is because of his limited acting skills.
He is a decent actor for supporting roles. But he is not talented or charismatic enough to carry a series by himself. In short, he is boring and there is little that he offers for the role.
If you look at his film and series career, he’s never really excelled. He played Jango Fett and some clones in the prequels and then fell into obscurity.
I was surprised to see him in Aquaman. But, again, it was just a supporting role and nothing to brag about.
The truth is we didn’t need this series and we should focus on other characters.
