Many good things look ugly to people at first, because their instincts steer them away from the unfamiliar. If you find yourself thinking, "this is objectively good, but ugly", give it a little time.

Unfortunately, much of what is called modern design isn't objectively good at all; it only looks the part, to people who don't pay attention. Villa Savoye, probably the most famous example of modern residential architecture, didn't meet even the most basic requirements of being a good house--it failed to keep out the elements.
