Tewder: The ROM's mandate, as I've pointed out previously, is carved in stone at the entrance to the 1934 wing and includes both the arts and the natural world. In singling out art, I was responding to the issues that TYKYTAKY admits he has with accepting part of that mandate - the Museum's use of contemporary art in their World Culture galleries as an entry point, and therefore central, to appreciating those collections.
In the Sigmund Samuel gallery, for instance, the visual messages given out by Benjamin West's 1776 painting The Death of General Wolfe are interpreted in print captions by several people living today, including an Aboriginal Canadian who comments on how Aboriginal people are portrayed in the painting. Deconstructing heroic myths created by dominant, conquering groups through their propaganda art in this way brings a reality check and a breath of fresh air. Clearly the controversy created by Into The Heart of Africa nearly 20 years ago is something the institution learned from. I certainly saw that when curator Lisa Golombek explained how the old way of displaying the Islamic collection was wrong, and was abandoned when it was time to display it in the Crystal, during her talk at the Colloquium.
The Gallery of First Peoples, just across the Rotunda from the Sigmund Samuel, has a good display of contemporary Aboriginal art - right up front and to the right as you walk in. And items from the ROM's historical collection have been selected by members of the Aboriginal community, displayed, and interpreted by them for visitors. Again, contemporary art and historical objects are central and used as entry points to the collection.
Though TKYTAKY sees the ROM's inclusion of contemporary art as "tenuous" - only three major institutions should, apparently, be allowed to treat it as central to their mandate ( which three? - he doesn't condescend to explain his restrictive quota system ) - the reality, at the ROM, is thankfully otherwise. Art is out there, it's on the loose, it's powerful ... and it's coming to a cultural institution near you folks!
Also, to pick up on your final point, of course buildings that function successfully can be criticised on the basis of their external aesthetic. All criticism either passes muster or fails on the basis of what it argues, not by the fact that it is being made.
