I tend to agree with you
if a city consists entirely of International Style buildings, however as part of the tapestry of a modern city I think the modernist structure is a beautiful addition. Take the public library in Des Moines, Iowa designed by David Chipperfield; if the city consisted of only similar buildings the city would appear cold, however if the style is used sparingly I feel it can add a lot of "flair" to a city scape.

I think you might be blaming Bauhaus for the shortcomings in materials available to architects in the 1930s, the technology didn't always meet their vision. I will give you one thing about the International Style, it gave us the abomination that is the architecture of Frank Gehry even though he falls a bit off of the International Style bandwagon. I don't love everything about the International Style by any means, but I feel the principles of minimalism is viable.
Also the Marina came almost 40 years after the Bauhaus was disbanded by the Nazi's. I think a better car to refer to as modernist is the VW Beetle or Porsche Type 64. I feel car design was impacted more by the oil embargo and that wound was worse than that of what could be inflicted by any Architectural style.
Personally, I don't really have an architectural style I like better or less than any other style. If I were forced to choose, I would probably pick Gothic, Georgian, and Art Deco the only style I dislike is Deconstructivism.
I like the blend of glass and steel that has developed out the International Style, I think if the Bauhaus was around today instead of the 1930s you would like it more. I love the glass curtain element as it exists in my own city.
Like our city hall which is commonly referred to as the ice cube.

I rambled a bit, but what I guess it boils down to is the fact that I like where the Bauhaus has taken us. Some of my favorite modern buildings are rooted in designs fostered at the Bauhaus.
