I live in Brighton so I'm surrounded by this type of show for real... every day. It's not shocking or filthy or any of that. It's just life and above all folks, it is just a comedy programme!!... for a laugh so lighten up. If you're offended, don't watch it. A gazillion other channels to watch.
Maybe the Gay scene has a different sense of humor but I didn't find it funny or particularly well written. Its even worse than Vicious that starred David Jacobi & Ian McKellen which is an achievement in itself.
I watched because I'd never heard of it until you. I found it held my attention and was very fresh and different. The i button described it as a drama not a comedy.
PS who is the guy on crutches, I recognise him from somewhere?
