When the gang of cowboys ride into town the street in front of the marshal's office is very narrow. Later after the cowboys ride out and Matt and Chester get up off their chairs and walk across the street it's about three times wider.
The gunshots during the gun fights were especially weak. They did not have the sound effect. More like the kind of sounds made by movie guns before the sound effects are dubbed over. Since this episode was filmed almost entirely on a sound stage all the sound effects were a little off.
