The original Archie comics debuted in 1941 (i had to look that up) and aimed to create characters who were "ordinary kids" that real ordinary kids could relate to. I would say its original readership would have been tween - between 10 and 13 or 14 - and teen boys and girls. By the time i saw Archie Comics in the late 1950s and early 1960s, i think readers were probably mostly at tween girls and a few tween boys, since the content would have been considered too "mushy" by most boys.
So, yes, "Archie" is old-fashioned and, perhaps, child-like.
The characters were mostly high school kids (in the US ages 14-17), but included teachers, the school principal, parents, etc. The main characters were the red-headed Archie who had crushes on the blonde girl-next-door Betty and the brunette elegant and spoiled rich girl Veronica. His side-kick was the goofy Jughead, who wore a REAL felt beanie (not a knit cap). And his nemesis was the arrogant rich kid Reggie, who assumed that Veronica was his.
So "Archie's Girls" represents more innocent and optimistic days, when exchanging a kiss was a really big deal.
