It's unfortunate. They had a real opportunity and instead created a lifeless soulless building that stands in deep contrast to the subtle memorial next door or Calatrava's soaring transit hub. Too many sacrifices had to be made for this tower. The fortifications at the bottom (20 floors of concrete with a glass covering) are hideous and the removal of the decorative aspects to the spire make it look like a giant syringe.
Not to mention we really didn't need the downtown office space. The Financial District is already half the price of Midtown and firms who want a downtown presence are now looking to more exciting neighborhoods for young workers like Chelsea and the East Village.
