This movie is great, until the characters start talking. I don't blame the actors. I blame the material.
So, it starts off okay, with a car chase. And it ends okay, more action. In between, the murder investigation moves at a snail's pace, as the movie decides it's actually a romance. Don't get me wrong, I like romances, when done well (hint: don't have the characters just sit around and talk about their feelings).
GIRL: I like you, but I'm scared to get close.
GUY: Me too. Oh and by the way, your dad hates me.
DAD: I hate you. Many years ago, you beat up a guy who was drunk and disorderly, after he picked on your female police partner and then took a swing at you. I didn't even really like the guy. But still, I hate you.
This is not too different from the actual dialogue.
