The world of Archie is perpetually 1950s, but without any trace if prejudice of discrimination. Gay or not, who'd mind spending time there?
Hell who wouldn't want to live in a 1950s that has black people, Ninja Turtles, video games, the internet and women that look like they were drawn by a legendary pin-up artist.
Indeed Archie and the gang have time traveling beanies, dimension hopping diner stools, cross country RC car races and that's just in Riverdale. You expand a bit you get mystery solving rock'n'roll bands dressed in lingerie and sexy witches. There's a reason this shit still flies in 2010, and it's because it's still comic books in the most traditional of senses. I can't think of a comic book franchise not about superheroes that is more recognised than Archie and it's nice that it still exists.
