I believe you are being a bit to "generalist" in your viewpoint of modern architects. Modern architecture was the era breaking away from ornamental periods (Victorian and Gothic revival) focused on minimalism and machine. It was the period that included two world wars, so the early part of the modern architecture was "boxy" due in part to the materials and structural limitation of the time as well as the focus on building for the middle-class. In the later part of the modern era design evolved significantly. Just take a look at Alvar Aalto, Eero Saarinen, and Frank Lloyd Wright (later works). You can also see evolution in non-building designs in this period from Robin Day and Charles & Ray Eames who help usher in molded plywood. Many Scandinavian Designers including Arne Jacobsen and Poul Kjaerholm brought us new techniques, shapes and material combinations. The Modern Design era is so much more then rectilinear boxes. If you want boxy go no further then Colonial architecture and then come back to the Modern designs and you will see the simplicity, openness, and how the buildings bring more unity between the inhabitants and the nature surrounding them.

I agree. Curves are so "pregnant" with anticipation and other feelings. Lines and right angles can never accomplish what curves can. There basically are no right angles in nature. The cold designs you talk about are not built to be lived in. They are built to be seen from an alienated distance. And believe it or not, I actually love the lines and angles of modern architecture. I just don't think it's done well enough. The person is lost in the design.
