When I first started watching the show, the host struck me as very odd - too excited, hugging trees, etc.
But, it turned out to be a feature of the show, not a bug! Pete loves his trees, and it is abundantly clear that he loves his clients.
His vision is astounding, and his creativity is limitless. The crew really knows what they're doing, and every treehouse on the show is breathtaking.
My only complaint, and it's a small one, is that the crew is occasionally forced to act out scripted lines, but it's a fun show, and it is forgivable and doesn't really detract from the overall feel.
If I had $80,000 to spare, I'd call Pete in a second.
