Typhoon, I completely agree. The inside of the WTC was awesome, and the whole complex was just an engineering marvel. The aesthetics of the buildings themselves on the other hand, left alot to be desired in my opinion. Don't get me wrong, I still shake with rage when I think about the towers' destruction and the people I knew that spent the last few moments of their lives there. That said, they just didn't "fit" with the rest of the skyline, and they dwarfed the Woolworth building (my second favorite building in the city after the Chrysler building) into non-existence. Nowadays, the Woolworth building is front and center.
I would also prefer that they didn't build some new gigantic building there. A relatively small memorial would be nice, but another mega sky scraper, no thanks.
