Gary Stu
Anyone else think Johnny is a bit of a Gary Stu? http://tvtropes.org/pmwiki/pmwiki.php/Main/MartyStu
He's heroic, he's brave, he's polite, he's intelligent, he's good-looking, he's a great fighter, he's rich, he's responsible, he's forgiving, he's empathetic. Women all love him, men want to be him or are irrationally angry with/jealous of him.
I cannot think of a single flaw this man has.
His brother was portrayed as a nice guy with a good head on his shoulders, as someone who understands the people who work for him and is generous with them.
Then it turns out Johnny is his brother and suddenly he's this irrational, bumbling idiot who doesn't understand his men and has no business sense.
