I watched for a few minutes.
What I saw was a bunch of weird spectacles taking place in the rain: gold statues of not very famous French women popping out of holes beside the river; a number of women singers performing on altitudinous platforms far above and away from the river; weirdly dressed BMX bikers and acrobats doing what they could on the greasy deck of a vessel; and a bunch of soaking athletes on boats waving at no one.
Other than the performers, did anyone attend?
I actually felt sorry for the French. And for me, that takes a lot. What a catastrophe.
