Although it's perhaps not in the same class as The Searchers or Rio Bravo, this is still one of the Duke's better westerns.
Most of the classic western ingredients are here: broody young gunslingers, stampedes, posses, brawls, wagon trains etc. It's good fun for all ages.
The picture has slight grain and a few speckles in a few scenes. But it shouldn't spoil your enjoyment.
In fact, considering the age of the film, the picture quality is probably as good as can be expected with vivid colours and a sharp picture (I suspect a lot of effort went into cleaning it up)
The mono soundtrack is a slight disappointment. As the film's rousing score would have benefited from a 5.1 mix. But it is a good mono mix, with lots going on, clear speech and no hiss or crackles that I noticed.
The extras are minimal, but considering the low price of the DVD and the fact that most of the cast are dead, this is probably nit picking.
Overall, this is a worthwhile purchase for any John Wayne or western fan.
