I am into interior design, it is why I started watching it.
I am not familiar with American mass culture, never saw these "celebrities". I just had no idea. I did not expect them to be so fake, obnoxious, vulgar, greedy, primitive. Their obsession with ever larger closets would be funny, if it was not so off-putting. Are they overcompensating for something? Realtors are the only people with human, intelligent faces there. They provide very nice contrast to these 'celebrities''.
Overall, I liked the movie, because it is very educational, somewhat entertaining (at expense of these "celebrities"), the photography and directing are very good. Some of the houses are as vulgar as the celebrities, but some of them have excellent, exquisite design. It was fun.
