So much disdain for LA museums here. Some of them are outstanding.
The Getty Center - It is a collection for connoisseurs of art --- not comprehensive, but only the best examples of their kind. All of the art is impeccably preserved and presented. The cases, framing, lighting, and educational materials set the standard. As for the building, it is a masterpiece of its own and worth the trouble.
The Getty Villa - This is my favorite LA museum. The setting is secluded. The collection of antiquities is one of the best in the US. The presentation is also remarkable. No expense is spared in how the art is displayed or in how the building has been outfitted. The ocean views from the Villa give you a sense of what it must have felt to be a Roman elite.
LA MOCA - One of the best post-War art collections in the world, though it might appeal more to art historians than art audiences. The building is unassuming, but it is finally getting the recognition it deserves. (The architect of the building won the Pritzker Prize this year.)
The Broad - One of the best post-Warhol collections of contemporary art in the world. The best examples from all the top artists, beginning more or less with Warhol. This is a collection meant to appeal to art audiences more than art historians. It is pure spectacle.
Norton Simon - Simon was the preeminent art collector of his time. The collection is a testament to that. Almost every piece attests to his eye for art and his taste level. Like the Getty Center, it is a collection for connoisseurs of art, but at a much smaller scale.
LACMA - an encylopedic museum, modeled after the Met. Worth visiting alone for two pieces --- Burden's Urban Light sculpture and Metropolis II. Probably the best LA museum for people watching. In the process, however, of shutting down its main building as it prepares for construction of a new building.
See not so bad. The other thing worth noting is that LA has become over the last 20 years one of the top centers for art production in the world. As a result, the galleries here function almost like museums of the now. The top galleries in LA are Blum & Poe, David Kordansky, Regan Projects, Maccarone, Gagosian (BH), and Hauser & Wirth.
