That building has some good qualities. However, when confronted by its overwhelming feature: at some distance, re; East Boston, South Boston, Quincy, etc, those good things get drowned out. That geometry isn't particularly good. And that's being kind. i'm dubious if adding height, short of setbacks, and 700, 900 or 1,000 feet could fix it.
Of course, then--it would overwhelm the skyline.
Citydweller -- No -- what makes the Hancock aka 200 Clarendon St work:I suspect that exactly why the Hancock tower works, the height (~780) makes up for the excessive width. The same could have applied here if wasn't out of context with the immediate skyline.
