I wont get into the show too deeply as there are lots of people who have done so. It's good. GREAT even.
My one comment will be about the people saying "There aren't any straight people in the show" which is entirely not true. There are just as many straight people as there are any other sexuality in the show. I wont put my opinion one way or the other, but people saying that 100% did not finish the show.
OH, and the notorious "Episode 5". It's specifically said that it's "The way people are without dreams". It isnt saying people are evil at heart or any sort of way, it's saying that their dreams give them hope. It's what keeps them going.
