It was a bad decision because of how they designed and built it. I am hopeful though, because they spent a whole lot of money correcting some big mistakes. Plenty of complexes of that size around the world had rehabs for dumber mistakes. The biggest problem with the Ren-Cen was the lack of a transit hub there and at major points downtown to facilitate access and stop the easy transition from office to homebound car travel. This to me remains one of the stickier points in downtown liveability.
