Was Anna Kendrick's idea really that much of a breakthrough?
For me, the viewer, it felt like a DUH! sort of idea. All these people on the road so many days of the year, costing the company a ton of money in the annual budget. Why not try to make the job electronic?
The job had been around for a while, based on Clooney's age. In all that time, nobody in the HR department, nobody in IT, nobody in the billing department etc thought about saving money by firing people digitally?
Basically, the movie made it seem like Anna Kendrick's character made some sort of genius proposal, demonstrating her brilliance. But in real life, it would have been a no-brainer.
