Missed Opportunities to Create real Conflict...(spoiler)
I hated the way the film glossed over Kristen's drug abuse. David had a real serious choice to make, either send her for treatment or sign her release, and he blew it. The message here is that her new job at Bloomingdale's cured her addiction. Just like that. Poof!
I really wished that he had made the hard decision to send her to rehab and have her hate him for it (in the short run) or had her lie to him about the job and he calls her on it.
The whole idea that she's a hopeless drug addict one minute and then next day she's clean, with no repercussions, killed the film for me.
It reminded me of sitcoms from the 80's where life's every problem could be solved in less than 30 minutes....
