Among the elite nature documentaries, like "Wild Migration", "Wild China" stands alone because it is a comprehensive series of all China, region by region. Immaculate film-techniques wedded with pristine science. Exotic birds. Sweeping vistas. More than education, it is a visual wonder. The PRC must be congratulating itself for granting permission to film teams in the field because the product does more to sell China as a must-see tourist destination than all the Beijing Olympic ceremonies combined.
