Will Smith and Rosario Dawson won NAACP Image Awards for their performances as ill-fated lovers in this relentlessly-depressing tearjerker.  Smith stars as a suicidal widower wracked with guilt over killing his wife in a car accident while fiddling with his Blackberry, and Dawson come along later in the story as the new flame he's agonizing over getting involved with.  The picture plays like a variation of The Millionaire, if you're old enough to remember that classic TV series about a reclusive philanthropist who, with the help of this loyal manservant, Mr. Anthony, gave away a fortune each week to a needy stranger, anonymously.  Here, we have a rocket scientist, Ben Thomas (Smith), passing himself off as an IRS agent to perform seven random acts of kindness as a shot of penance.  He still plans to take his own life anyway, because he's eager to join his dearly-departed spouse in the great beyond.  The only reason this transparent film takes two hours instead of two minutes is that Ben goes to great lengths to make sure his beneficiaries are worth of his blessing.  Another fly in the ointment is the seemingly-inappropriate romance which unexpectedly blossoms between him and Emily (Dawson), the sexist, terminal heart patient in the history of cinema.  Among the other charity cases are Ezra (Woody Harrelson), a blind telemarketer who keeps his cool when Ben berates him; Coneeie (Elpidia Camillo), a battered woman too afraid of her violent boyfriend's outbursts to leave or press charges; Nicholas (Quintin Kelley), a sickly kid in need of a bone marrow transplant; Holly (Judyann Elder), a social worker with cirrhosis of the liver, etcetera.  You get the idea.  So, you do not have to be a rocket scientist to figure out how St. Ben will earn his angel's wings.  Your job is just to sit there and be manipulated by a patience-testing production that drag on long enough to infuriate you well before its warm and fuzzy moments finally arrive.  Between the schmaltz and muzak, this surprisingly-superficial message movie amount to a little more then a feature length public service announcement on the danger of text-messaging while driving.
