There's never been anything like it in Denver -- and not just because it looks like a futuristic spacecraft (or maybe what's left after one crashes). Even as the steel framing of the structure created by Daniel Libeskind and the Davis Partnership was going up, the Frederic C. Hamilton Building was a landmark. And as it came on line last fall, this addition to the Denver Art Museum was reviewed in newspapers and magazines around the world. Although many of the reviews were negative, as Oscar Wilde pointed out, being talked about is better than not being talked about -- and talk about the Hamilton they did. Some of the talk was about functional problems, and the roof does leak. But even so, the building has fulfilled its most important promise: raising Denver's cultural profile a full notch, maybe two.
