_Hello Sister, Goodbye Life_ is a solid film. It is based upon the 2003 book _Same as It Never Was_ (a.k.a. _Olivia's Sister_) by Claire Scovell LaZebnik; the teleplay is written by Nell Scovell (her sister) and Alan Mark Levy. More on this later.
The movie was shot in New Orleans shortly before Hurricane Katrina and is dedicated to the people of that city.
The set-up is a rough one: Olivia "Livvy" Martin (Lacey Chabert) is a bitter, selfish, sarcastic, 21 year-old college student. After her distant father and step-mother are killed in an accident, she learns that she was named the guardian of her 7 year-old half-sister Celia (Sammi Hanratty). Reluctantly, Olivia takes on the responsibility and, predictably, makes a complete hash of things to begin with. To compound the problem, Olivia's over-the-hill-model mother (Wendie Malick) moves in. The only stable positive, nurturing influence on Olivia's situation is her late father's friend Dennis (David Ramsey), who is an "uncle" to Celia; on the other hand, her boyfriend Joe (Adam Kaufman) encourages her selfishness and negative feelings.
There are numerous changes from the book which simplify the plot -- especially the romantic aspects -- and take the most bitter edges off the characters to make them more sympathetic, make the story more palatable to ABC Family, and to make the movie run in under 90 minutes. Because the author's sister co-wrote the adaptation, I presume the changes were largely in what Ms. LaZebnik's idea of the spirit of the book. Even so, the drama still bites and the humour from the characters and situations is largely preserved, albeit not as prevalent.
