As for Heigl, she was right the first time:
“I think that what she realizes pretty early on, when they kind of start dating to see if it's going to go anywhere and if they can make it work, is that he's a really nice guy with a big heart. He means well. He's a bit of a doof and he makes some sort of silly and stupid choices, but ultimately he means well. I think she starts to get his sense of humor. I think in the beginning they're kind of off, they don't get each other and she doesn't get his jokes and thinks he's serious and is offensive and whatever. Then she starts to realize, 'Oh he's actually really funny and charming in his own way and a very kind, good person.'”Isn't Heigl's empathy enough?
