The acting's middling, the direction poor, and the sets look cheap. Then there's the cinematography. They must have used really low-budget camera and film, because the DVD shows little detail, and in some scenes the white levels are so high, details are lost. Now, I love old black-and-white films that have high production values (Casablanca and Citizen Cane come to mind) but this film isn't in their class.
Now for the flaw in the plot. The gang's leader drives his white T-Bird to every crime they commit. Then why would the cops go to the trouble and risk of putting a stool pigeon in a gang, when it be easy for the cops to tail the T-Bird and catch the crooks in the middle of their burglary?
