The plot is pointless, as apparently they had money to pay for food the whole time. And they also could have just lived with the aunt, or found someone else for that matter, even if she was a little cruel. You suck it up. The brother (spoiler alert) was irresponsible and didn't have to let his sister die. She could have lived with anyone. Why couldn't he find a job? I don't want to say that that deadbeat deserved to die, but he did. Is that supposed to be the moral? Indolence kills everyone you care about? This was a cheap film, banking on an attempt to decimate people emotionally.
