I watched it live on TV, and saw what I expected, not what I would have liked : close-up views, people, which give no indication at all of the speed and power of such a train. They should have shown the whole countryside, so that we have the scale, and thus an idea of the speed.
Just seeing a "normal" TGV passing close by at 300 km/h is quite an experience. I wonder how 570+ would feel. By the way, they couldn't use an helicopter for the outside images, they had to use a biz jet...
This is one of my pet peeves : I wonder why today's image producers always make this same mistake of focusing on the detail, instead of the larger picture. If they are sent to film a volcano erupting, they will show you the lava, never the mountainous clouds of ashes above the volcano. You never get to feel the scale of the event. Am I the only one to be bothered by that ?
