Compared to Ghost from 1990 this movie is really really bad and pointless.
But otherwise it's not bad and good enough to kill time when there's nothing better to do.
My main problem with this movie is that it's too "liberal" and it shows, so here it is, she doesn't pay any attention to the road and..... opps there's an accident. So whose fault is it? One would think the driver is at fault but not in a liberal world. It's always someone else fault, in this case the owner of the car because the car needed some repairs. But what about her not keeping her eyes on the road? What about her decision to take this car instead of calling a cab, after all she is a rich girl, she can afford it?
The ghost was needed to erase her guilt of killing her boyfriend and moving on with her life. She is a good girl, she deserves it (sarcasm).
Accidents happen, it's not a reason to ruin someone's life but hey..... let's put the guilt where guilt is. Why isn't it so simple, Hollywood?
