Nobody could be as stupid as Nate...
...when he finds Becca's thesis and kicks her out of his house without giving her a chance to explain. Why should she have to explain anyway? If he couldn't see that Becca really loved his daughter then he's a moron.
Guess they needed something bad to happen to carry the story but this turn of events was implausible. As I said before, NOBODY could be that dumb. But I'll admit that I liked the movie, including the little girl with the "annoying voice" (see below). How could anyone say that about her?
