This COULD have been an exceptional John Wayne film, as the plot was so unusual and was based loosely on the exploits of oil fire expert Red Adair. The idea of him working as a man who travels the world to put out oil fires is pretty cool! This was a very nice change of pace for The Duke and the film had some wonderful moments. However, while the script SOMETIMES offered a lot of new and interesting moments, at other times it was very clichéd and formulaic--cheapening the exploits of Adair AND making it just another mediocre late 60s/early 70s John Wayne film. Now understand that I really like John Wayne films, but I must admit that aside from THE SHOOTIST, all his films after THE MAN WHO SHOT LIBERTY VALANCE were mediocre and formulaic--so much so that they offer nothing particularly new (even TRUE GRIT which garnered Wayne an Oscar even though he'd made many better films). Even one of his films I really liked from this era, ROOSTER COGBURN, is essentially THE African QUEEN set in the old West. And what formulaic elements do these films have in common? Well, how about a way too old Duke Wayne getting in a fist fight in all these films (and he was into his 60s), macho arguments among the manly actors about who is going to do the "selfless" act (whatever that might be), an occasional over-reliance on comedy and John walking through the film as if he's in slow-motion (which, at his age, he was). No, Wayne didn't age very well in these films and his fans watched them because they loved the actor--not because they were outstanding films. That's exactly why I watched them.
