This is actually not a bad movie! Unfortunately the title leads viewers to expect more about 'the attitude of the super rich toward those outside of their circle' which never really happens.
What we have is rich people interacting with other rich people! And this just turns the plot into a drama of lifestyles of the rich. There are plenty of television shows that do as much. The only character that seems to have a concept of life without money is Phillip Miller played by Steve Guttenberg - he goes to work to maintain his families lifestyle. The other characters just party.
With the title 'Affluenza' I was expecting to see spoiled self indulgent rich people seeing the 'working class' and treating them with a decidedly cavalier attitude. Doesn't happen! They just stick to themselves and create the typical misbehaving rich people story. Ho-hum! Seen this way to many times.
Most of the acting and dialog is good but the story just slides along on its dramatic path with predictable turns. It has it's moments of being good and Ben Rosenfield is rather good as the cousin Fisher Miller finding himself surrounded by the affluent family he's staying with while he tries to become a photographer.
