I don't care much for Jeff Lewis, but sex appeal are not why he keeps my interest.
His ability to tear down a rat trap (literally) and create a beautiful living space is why I pay attention to the show. The work he puts into the home itself in no way reflects his dysfunction and anxiety, it was even mentioned on the show how peaceful and comfortable his homes are.
The over all designs are well thought out and from what I have seen visually appealing. This is not a new concept, what he does is a form of art, only his medium is construction and design. We all know tons of crazy folks have been successful artists through out the years (or creative people such as Jeff)
I love the show. I don't find Jeff to be "fem" or "flaming" at all. If he was, and the outcome of the homes were the same I would still watch. I am not that hung up on things like that when it comes to a person and their ability to do a good job. His works speaks volumes as to his ability to make things work.
