It's presence and location spoils the views of much more traditional and impressive buildings, and its purpose means I really think something more traditional was called for - it's the City Hall for London. A two thousand year old city full of history being governed from that monstrosity... I can forgive to some extent, buildings that are simply office buildings like the Shard or Canary Wharf and which probably won't be there in one hundred years - but the City Hall should have been a building for the ages.
