Bob Steele was unusual compared to other B-movie stars. He was a very small man and didn't sing....but he was an accomplished stuntman and horseman and could make fights and horse chases look very realistic. He also was rather laconic in his films....talking little and letting his fists do the talking for him. I generally enjoy his movies though must admit he made a few stinkers. The "Gun Ranger" is somewhere in the middle.
Dan Larson (Steele) is a lawman who is getting very frustrated. Again and again, he captures baddies and the judge lets them off on various technicalities. So, after realizing he'll never get justice by working with the system, he quits and goes on a vigilante campaign in order to discover who is behind all this.
The film could have been better. The fight scenes were very nice (as usual) but there are less stunts and action than you'd expect...and instead it seems a bit talky. Plus it had a horrible cliche...the woman who just stands there doing NOTHING while the hero and baddie fight it out right in front of her! But it's STILL enjoyable and worth seeing.
