Overall, it was a decent show, good even.
What makes the rating drop like Titanic is the production or rather video editing.
I felt forced to fast-forward most of the episodes because of it and no show is considered a good enough should for good rating if you feel that need.

All things considered, I loved the diversity (even though it felt they tossed in a few foreigners just for the sake of it so they could be somewhat true to their claim about "regardless of gender or race").
As for the gender equality, well.. yeah, no, you can't quite compare, in all honesty.
It showed quite visible the gender difference in some of the games.

The last episode was one of the better ones, because it felt more honest and less scripted, because that is the second reason for low rating; it felt scripted a lot of times. Ep was more down to earth and to be honest, humble somehow.
Compared to the beginning as it felt like a huge brag-n-clown-fest.

I still recommend to watch this, but its not like up there.
