The developer in their attempt to have a 'starchitect' quality attached to the project, has ultimately failed.
Instead of going with going with Herzog and De Meuron themselves, they go with a former employee associated with the firm - whose designs are less than inspiring. To me, this is kind of like aiming for sex but ending up home alone solo with a night in front of the computer.
Close, but no cigar.
Anyhow, I think that it should be noted that box buildings don't necessarily have to be boring. Take the China Resources Building for example, a box yes but a pretty one at that.
