I very much enjoyed Jacob Phillips allusion to the smurfs. It was right on target.
He said that the production was banal. It was also incompetent.
It seems to me that the problem is that the Olympic producers understand very little of communication. A symbol means what it means in the minds of the people who use it, both the people expressing the symbol and the people perceiving the symbol. The two groups can have quite different understandings of the same symbol. A red circle is a patriotic symbol for the Japanese; it means "stop" for Americans.
The Olympic producers assumed far too easily that the symbols they used in the opening ceremony would be understood by people worldwide. How many people around the world are aware of the painting "The Feast of Dionysius"? How many even in France know about Sequana? If they were not aware of the misunderstandings that would occur in the minds of the viewers, then I think they need to have more contact with people outside of their own group.

However, I would like to add that it is valid to ask if the producers were really so clueless that they failed to notice the close resemblance between their portrayal of Bacchus and the Last Supper. This also applies to the scene with Sequana. Did they really think that everyone would think immediately of Bacchus and Sequana and no one would think of the Last Supper and Joan of Arc? There was a failure in communications and if it was not intentional, then the producers should return to school.
