It IS worth watching, just to find all the family relationships and the John Ford company regulars who pop up in unexpected places.
But Leonard Malton must have taken all his information from John Ford's version,which is not necessarily accurate. (Maureen O'Hara stated it best in her memoirs: "John Ford was a liar. If someone said there had been a lot of rain in Ireland, he would say it had been sunny. If someone said it had been sunny, he would say that it rained all the time.")
It is interesting to hear about the challenges it took to make the "Irish picture", as many studios referred to it.
The interviews with John Wayne's children are also very insightful to the set life, and to the importance of John Ford in their and their father's lives.
However, the story could have been a bit more insightful, rather that the general information that is rather well known. (For example, what EXACTLY was Maureen O'Hara mad at John Wayne about when she was supposed to slap his face, but slapped his hand and fractured her own fingers?!)
