The film opens with glimpses of Katniss in her daily life before she is involved in the games: how would you describe her life? How does she cope with her situation? What values does she seem to have?

You have quite a few questions here. I can make a general statement. District 12 is an impoverished coal-mining region in the country of Panem. Katniss lives a subsistence life of hunting and gathering to provide for her mother and sister. Everyone in the district leads a hard life mired in poverty and squalor. Katniss values her family above all. Both her mother and little sister are vulnerable and Katniss spends her time as provider and protector.
