The de Young is trumpeted as an architectural triumph - there's even a silhouette of it painted on the wall at the airport next to the GG bridge. I consider that building banal with the exception of the tower which is a bit interesting, but even that is compromised with the sunscreen they have that is right at my eye-level, so I have to lower myself just to look outside from the top of the tower - a bit ridiculous. It is a big box with almost no real effort to explore indoor/outdoor continuity with the surrounding park and has no relation to human scale, and the glazed little internal garden areas that humans are not allowed to visit depresses me. The number of awkward spaces is also unfortunate. That's not to say that the jazz wouldn't be good :) (And the cafe has decent food in spite of their strange dishes) The park itself is beautiful (the largest man-made park in the world).
