When we saw the movie opening weekend, my mom pointed out an interpretation of President Business that I don't think I've seen anywhere else. She was saying that instead of being business like a corporate business, that he was "all business" as in being serious and no-nonsense.
I figured it was because Spoiler: if you've seen the movie the kid didn't know what his father did at work besides generic 'business'.
Saw it yesterday -- pretty brilliant. Graded it a ten, I don't have anything much to add that hasn't already been said.
