Film critic Dennis Schwartz liked the acting and wrote, ""The Mob" covers the same territory as "On the Waterfront" three years after "The Mob". It is adapted from the novel "Waterfront" by Ferguson Findley and directed with a flair for lively action scenes by Robert Parrish. This ordinary minor film noir holds together until one twist too many turns it into one of those old movie theater chapter serial-like endings ... Broderick Crawford is believable in this heroic role and moves his character into a noir figure by his hard-boiled, no-nonsense approach to the dangerous situation, where he's not in control of his destiny. Ernest Borgnine has the natural look of a shady individual to give his role a sinister force. Neville Brand as a strong-arm enforcer for Borgnine adds to the violent atmosphere. The film has fistfights, tough talking thugs and cops, and a bleak view of the corrupt docks. The brutality of both the criminals and the police is what gives the film its shock value and special feel. Otherwise it's your ordinary violent crime film."
