I like the scaffolding. Makes it easier to smoke in the rain.
It might not look nice in photos, but the semi-permanence of scaffolding in NYC has resulted in some pretty nice-looking scaffolding structures, some even with lighting. (John Wilson made a great episode on that.)
Beyond that, as a pedestrian you start ignoring the "ugliness" pretty quickly. The scaffolding almost feels kind of cozy, and protects you from the elements.
