This documentary starts with events long before I was born, covering the US's nuclear weapons testing in the Marshall Islands. I had not known about this and the USA's behaviour certainly looks deplorable. I'm not naive, I know that all countries do bad things, sometimes with ill intent and sometimes through perhaps misguided good intent or pragmatism.
However as the film moves closer to the present day, it portrays China as basically a good actor which is a victim of the West's evil. I know this isn't true and conclude that Pilger is an unreliable narrator. There is an occasional acceptance that China isn't a Utopia (Pilger mentions briefly the human rights issue) but generally this is an extremely biased polemic against America. And realising this makes me distrust the picture I was given about the things of which I was previously ignorant.
In conclusion, if you treat this documentary as pro-China anti-US propaganda and as heavily biased, knowing that a fuller picture is needed to form an opinion, then it's watchable enough and can be used as one resource. However, if you trust what Pilger tells you verbatim you will not have an honest or reliable view of what is a far more complex situation than Pilger presents. There are more things in Heaven and Earth Horatio...
