Before watching the movie:
I thought this came out later. I seem to remember a poster for this movie being up like it was new when I was in college. Maybe I was mistaken about why it was up, or maybe a movie with a similar poster was out at the time. It’s not a very original poster design.
Anyway, there are few better ways to manufacture conflict in a romantic comedy than to have the romantic leads have opposing goals they’re hiding from each other, and this is one of the most basic forms of that. He’s made a bet that he can make her love him in 10 days, she’s trying out a relationship destruct plan for an article she intends to write. And there’s a lot of quirkiness along the way I guess.
