Hugh Pearman, London-based design critic and author of several fantastic architecture books, was recently in town reviewing another NYC project , and decided to stop by to check out the progress on the High Line.
Pearman compiled his initial thoughts  about his visit on his Web site. In the review, he's forthcoming about the doubts he had before walking the High Line, but admits that the project quickly won him over:
"I had worried. It's only natural. The lure of dereliction, its especial beauty, is its very isolation and tragic transience. By this token, the idea of turning the secret world of Manhattan's High Line into a linear, permanent public park could surely not succeed. But now I have walked the first, and nearest-complete, section. I am impressed and delighted."
