The reason people love films like Bonnie and Clyde and Hard Times is because it portrays people fighting back; fighting back against a society that has not given most of them a second thought. Modern movie-goers can identify with these characters because their governments (from wherever they are from) oven overlook millions of their own citizens who are fighting on a daily basis to make ends meet. This is why the characters in these films are appealing. I don't recollect anyone ever rooting for the police or the government in the theater I watched the film in; and I saw the film with a cop buddy of mine.
The film is a tad violent, but these were violent times. Based on the recollections of three bootleg brothers, it paints a fascinating picture of Virginia in 1931. Don't worry, this aint the Waltons.
