I think perfection is in the eye of beholder, everything is too relative to call it perfect. What's the best place on earth to me, can be someone else's hell.
From personal experience,I guess the show might be entertaining but the society they'll make would fall into something similar to what those people come from. As open-minded as they claim, at the end of the day people are judged by their background, race, religion, etc. Whoever with power will abuse /misuse it and ruin the promised bright future. I know i won't try watching that show,I'm living in a similar hell and I don't need to be reminded.
