We had an excellent temporary art exhibit over a decade ago called "Gifts to the Czars". Beautiful, gold, gaudy stuff...just ridiculous opulence.
Yes, there is that aspect of design and decor present in much of the film as far as the actual physical backdrop in terms of the buildings, Winter Palace. etc. It doesn't offend me morally because I choose not to think about the fact that one square foot of any room on the grounds probably cost as much as it would have cost to feed an entire serf family for five years or more. Art is art, and while my personal tastes usually are more in step with primitive/folk art, I can appreciate the splendor of the old Russia.
I saw a Faberge display when it was on loan locally and thought they were very beautiful - just not something I want in my home.
Despite the controversies about how some of the art at the Hermitage was obtained, I think the most interesting thing I will learn from the film (since I'm now more interested in their collection) is what exactly is it about the non-Russian works that meant something to the different Russian rulers over the years. You know how Russian works of art and literature reflect their own history and culture. It is quite another thing to ask what the things they covet say about them.
One day I will probably go to St. Petersburg. I'm not putting my dog in quarantine or a kennel...and I don't even trust my parents to watch him. One day after he has led a long and happy life, I will go. I hope Putin is still in power.
