I wonder really if by trying to make the program a bit more sensacionalist they are not invading the realms of a Life of Grime, or probably reviewing cases of people who would not fall into the normality bracket (in psychological terms)... A bachelor who fell into a vicious cicle ending with a disgusting house it's OK (because it is in his hands to change it if he wants to) but some serious hoarder may benefit more from a visit of a psychologist than from one of Kim and Aggie.
But find the program very interesting, specially because of the techniques they use to clean [my Monica Gheller spirit talking )
