How is everyone so sure?

I've been reading a lot about how this show is supposed to anti-polygamy. I'm not sure why people are getting this idea. Is there a promo I missed? 

I though this show was about how polygamy is allowed in Islam and how a man can love both his wives and give them both happiness. I am not a fan of polygamy so I don't want to start this show. But if this show is anti-polygamy then I do want to watch it. 

Can anyone clear my confusion? I would appreciate it. 

The show does not promote polygamy and its not an anti polygamy either
