Exactly my thoughts. If we give FLW, modernist, and postmodernist architecture a pass on those criteria... why not to the McMansions? After all, they weren't designed in the 19th century... The problem might be the lack of coherent design, the cookie cuter approach, and the cardboard construction, but I don't really buy this critique ...

Because one of the characteristics of McMansions is that they (poorly) copy the style elements of classic designs while ignoring the rules that governed those designs.

Modernist and postmodernist architecture isn't trying to imitate classical mansion architecture.

But then, "copy the style elements of classic designs while ignoring the rules that governed those designs" will make it automatically bad, and IMHO many aesthetic trends started like that
