Answer: Don’t make it about four teenage guys. Make it about four teenage girls.
I wrote a post about that Inbetweeners reboot that people have been talking about recently. Basically, the only way it could work is if it were done with four girls. Admittedly, the argument in the post isn’t perhaps so well stated; there’s a lot of things in it that I take for granted, because I’m still working out how to articulate them properly. But I stand by the basic idea nonethless.
(About a year later, give or take, Channel 4 aired Derry Girls, to massive critical acclaim. It’d be oversimplifying massively to liken to The Inbetweeners, or to say that its popularity was just because it was about four girls, but I do think it at least helps to prove the above point a little bit.)
