This is the second part of a two-part review of A Better Life. The first part dealt more with the background issue of illegal immigration, whereas this part focuses more on the movie itself.
In the movie, neither the illegal (representative of all illegals, but particularly those with upright motives) nor the police (representative of the legal system, including courts, prisons, and immigration) is entirely at fault. Both are stuck in an imperfect, human system.
The viewer is led to sympathize with the illegal man, an honest landscaper who wants nothing but to work hard so that his one son can have a better life. He's away from home; his wife left him when his son was little; he has next to nothing; when he does acquire something (a lawn business and pickup with equipment) it gets stolen from him. And yet, the movie does not excuse what he does wrong nor does it try to show him as a man victimized and ruined by the consequences of his actions.
