The Green Green Grass Is Crap because -
First: it asks us to buy into the "Only Fools And Horses" myth. So we have Boycie and Marlene escaping from Peckham and living in the countryside. Fair enough thought I.
BUT - it then asks us to "Buy out-of" the "Fools And Horses" myth by giving the couple a son, and we all know that Boycie was a Jaffa. (Seedless).
Therefore, to work, it has to be either one or the other. It can not do both at the same time.
