The bungalow home and the colonial homes that he praised, I didn't find the aesthetics to be pleasing.
To me, the photo from wikipedia is more like the McMansions I think of as ugly:

The wiki example has the siding that covers the entire side combined with the Greek columns in the front entry. It's a weird mismash of gaudiness. The garage also overwhelms of rest of the house.
Like another poster mentioned, some of the awkward boxiness is due to homeowners wanting 3500+ sq ft homes on small lots that are 1/3 and 1/2 acre. An architect no matter how talented is too constrained by the lot dimensions to avoid designing an oversized out-of-proportion box.
