Coates have a great prose, he writes really well, but if his Superman is anything close to his Black Panther we have a lot to worry.
His Black Panther was indecisive, ineffective and couldn't solve anything without the help of half MU. T'Challa would just walk around asking for help, getting scoulded by everyone until they agreed to save him.
I'm ok with a Superman movie where the idea of the character itself is questioned, as long as I also have a more heroic take on the character as an option.
