Anyone my age (55) and older that dislikes this show needs to think back to their own 20s and remember how clueless they were. This show is like a beginner's guide to having (and what to aviod in) a sex life and/or relationship.
I'm impressed by what I've seen so far (I'm writing this while watching episode 4). Yes, the show appears to be simplistic and has a plot that is mostly beside the point, but I think it's important to embrace this simplicity if you are going to enjoy the show.
The show is predominantly about human sexual interactions, many of which are transactional in nature. Regardless of Gregg Araki's filmography, I would say this is more a millenial- rather than a gay-oriented show; "Queer as Folk" this is not. What's even better, this show is both old-school and Progressive with a capital "P" at the same time. Old school because the situations these characters find themselves in have been played out repeatedly for ages. Progressive in that gender stereotypes are out the window, for instance the most masculine character in the show is also the most emotionally vulnerable.
Hopefully this show will continue to explore a broad gamut of the human emotional spectrum.
