The curious aspect of this for me is that I generally think Disney has done Arts and Crafts well in their theme park and resort settings and it has made for appealing environments, whereas I really don't have the same reaction to their attempts art Art Nouveau. It's also very appealing to visit cities like Vienna and Brussels with impressive examples of Art Nouveau and a couple of weeks ago I also visited the Quinta Gameros in Chihuahua, Mexico which is basically a museum of imported Art Nouveau style by the pre-Mexican Revolution elite. I'm not sure, however, it seems like an appealing style nowadays in which to design and furnish a home and in which to live. I'm not sure if this makes it more jarring when it's imported out-of-context to a theme park environment.
While they have the same roots, I wonder whether Arts and Crafts as a style (with several iterations) has just managed to remain broadly aesthetically pleasing for longer and easier to translate for new environments and even times than Art Nouveau. People also still really do seek out Arts and Crafts home and design and want to live surrounded by it. Art Nouveau did fizzle out pretty quickly, and my reading of early modernists and even functionalists is some respect for William Morris but absolute horror at all the curves, flowers, and peacocks of Art Nouveau!
Again, I hope not to have derailed this thread too much on what may just be a question of personal taste!
Huh, really?! I thought I was the only one! Maybe we'll have to arrange a Benelux WDWMagic meeting!
