If any trailer says that Rolling Stone gave it a good review, I already know its terrible. RS gives a positive review to *everything*. The producers went through the list: Time, no; Newsweek, no; NYTimes, no; LATimes, no; Entertainment Weekly, no; well then just run the review from Rolling Stone.
Too bad it was supposed to be a imaginative simili to how the loss of both parents might be perceived by a child. Sandra Bullocks character represents the missguided "cheer up"s, Snipes character represents the fear of death that tends to haunt a child that gets death too close to home in the wrong time of development, the three seashells, and ofcourse many other "reality has changed" metaphores symbolizes the many changes in lifestyle that a child in that position goes through (it's not enough to lose ones parents, you need to move in with a relative which often means change schools, leaving friends behind and things like that). It was supposed to be a profund heartfelt aid to people in pain and due to stallones lack of acting abilities it comes off as a slapstick sci-fi.
