I’m not sure whether or not you are familiar with the concept of Tai Chi, but it seemed the first half, the “boring” half is more indicative of that concept. Tai Chi is more about finding and focusing inner energy, which would make sense, since the second half of the performance seemed more energized, representing the release of the pent-up energy. In addition, the above post seems to represent on a large part the American expectations for media, a greater emphasis on action and movement.
