Totally agree re why can't they just put some 'normal' guys (and girls) in there. None of the guys can string a coherent sentence together, and don't seem to have a brain cell between them, oh but they have good bodies so women will fancy them anyway 
The same with the girls, Camilla and Montana notwithstanding. The rest just seem all airheady and a bit simple.
C'mon Love Island, people can be good looking AND intelligent.
Having said that, I don't know many 'normal' people that would apply to go on Love Island.
