Not that anyone but other comic geeks are likely to care, but I knew from one thing that the show would flop.

This one thing showed very clearly that it was a show being pushed by executives that didn't understand the source material in the hopes of wringing an little cash out of the Inhumans since the X-Men were out of the running. At the time, that was Marvel's big push, to make the Inhumans popular so that they could take the place of the X-Men in fandom. Which was doomed to fail to begin with just like the show.

But, that one thing. Medusa. The second she was bald, it was obvious that the entire show was half-assed. Making her hair, the super power she has, disappear could be a decision made only by someone that didn't want to spend money on the character.

Which showed blatantly that the show would be low quality in every other way too. If you aren't willing to invest in your main characters, any show is fucked from day one. Anyone trying to make an Inhumans show, seeing Medusa and thinking "Damn, that hair is going to be a major CGI expense. I know! Lets shave the hair off! That'll fix it!" Is about as uncreative and stupid as it gets, and needed to find a job outside of tv and movies.

It's a freaking super-being show. And they went out of their way to make said beings as un-super as possible.

At some point in that process, someone with some authority didn't just scrap out as a bad idea and wasted a shit ton of money and time. It was doomed before it ever got the first scene filmed because the people running it were idiots
