Don't think anyone was watching it to complain about it enough !
They gave it a good attempt imo, but with the budget and CGI heavy effect characters such as medusa's CGI endless moving hair they had to drive the story
and re-invent much of the inhuman's ie medusa's shaven hair, kill off the cool looking reptilian guy Triton to save more budget and you have the main character black bolt who can't even speak.
These were epic failures of why inhuman's can't ever work, they were always 1 or 2 episode on fantastic four or spiderman animated series and others I think, usually just swapping out the character's a little bit.
The fans have suggested they work best on say agents of shield where they were originally mentioned, but now that marvel has its character's back like x-men and fantastic four and many other greats they don't need to mention inhuman's ever again.
