The quality of the interior layouts and that of the exterior expression are loosely linked at best in any building, so I don't see one as making up for the other where there are perceived deficiencies.
I do not begrudge anyone bemoaning the loss of colour on a building exterior (even though we all knew it was only temporary), and I think that dismissing visual "pops" as unworthy of consideration is also a mistake: any element of the exterior has to be considered for its part of the whole package.
In regards to this building being awkwardly massed: it's meant to be awkwardly massed. It's meant to be atypical, and eyeball-grabbing because of it. That doesn't mean that everyone is going to appreciate its aesthetic qualities, but I'm not sure that's what is being sought here anyway. Sometimes, just standing out a bit is a positive (to be weighed against everything else).
