My DS was an inbetweener, they even went to Greece last year to celebrate post Alevels. His friends are defo identifiable within the characters. DS is defo a “Simon” with a touch of “Neil” although he was sport at school so slightly elevated. He has a “Jay” friend and there are several geeky ‘Wills” he knocks around with.
I think “Inbetweeners” applies to most school years, because there will always be that social group that don’t quite make the “cool kids” but desperately aspire to them.
They are all at Uni now, would love to see a similar comedy about uni students, there was Jack Whitehall’s “Fresh Meat” which DS is binge watching before leaving for uni, but again a little dated.
It all changes at uni and often the r cool groups struggle, leaving the Inbetweeners to thrive because they are often the nicer kids anyway.
