If you approach the series as its real star being Josh Randall's sawed-off .44 Winchester, you'll like the reality that McQueen creates for himself in most situations. That gun symbolizes 'total non-conformist Western-character' and 'non-conformist bounty-hunter', combined. -A bounty-hunter who cares that he's actually tracking non-innocent criminals.
So in some of the episodes, he's more of a crime-solving detective.
But he's an absolute borderline-homicidal beast, when confronted. His sawed-off rifle is a fabulous weapon. And he's fast with it.
McQueen's acting is impeccable. He can make things like drinking hot-coffee seem like an adventure.
Sure, some episodes contain sappy sequences with eccentric-but-lovable characters, and romantic dalliances with goddess-quality, but 'flawed' women. The episodes' 30-minute length weakens a percentage of the script-plotting, however. Solid editing rescues them somewhat. You're plunged directly into a scene, then yanked out of it when the point of the scene has been made.
Check-out the first 19-seconds of the intro:
The first two chords of the theme completely sign-post; violent death has arrived... and the demonic visage of McQueen's face signifies; I just killed somebody and now I'm going to kill you, and like doing it.
All-in-all, it's a great series with some weaknesses. The sawed-off Winchester isn't one of them.
