For one, it's very predictable from the very start, and secondly (spoilers ahead if you somehow managed not to predict it would happen), the whole movie leads up to the chick marrying her love interest as soon as she starts to think she likes him. They've known each other, what, 3 weeks, tops? And none of that time was spent dating, she just kissed him, thought, "I think I like him" and proposed to him. Stupid. They tried to make it a typical female fantasy, but in all reality, who actually wants to marry someone they haven't even gotten to know?
