I liked this, but didn't love it. I don't understand Ryan's need for adrenaline that can only be achieved through being behind the wheel of a fast car. I liked Amy's sarcasm, but otherwise, could not really relate to her. Maybe that's why I liked their story, but was not super in to it.
It kind of bothered me how so many characters were presented as having somewhat nefarious intentions in the beginning, but that ended up not necessarily being the case. I guess that is somewhat life like, where no one ever really knows another person's intentions. So, I probably need to get over that.
