Anecdotally, the professors I talked to in the building hated it. Non-rectilinear walls and oddly-shaped offices made it difficult to put up bookcases and desks. The windows were all custom, meaning if one broke, it was difficult to replace. And, of course, the aforementioned leaks.
I was in the Radio Society and had access to the Green Building (50) roof. The Stata Center actually looks coherent from that angle, and you can tell that was the angle the designers and approvers had been seeing it from (in model form) the whole time.
