Zestless tale of how a babe is kidnapped in 1860s NYC by four boys who’ve banded together to head West looks like it’s poking around for a bonanza, but director Christopher Cain summons up little vitality from his unexciting cast. Earl Wallace’s teleplay just goes on and on, but the characters are only routine, their story unexciting. Funny thing is that all the ingredients are there. The babe, Mary Rose, grows up out West with no knowledge of her true parentage, and each boy has a stake in a good yarn. One boy, Adam (Jeffrey D. Sams as an adult, Michael Alexander Jackson as a kid, with each contributing credible perfs), wants to head West because he’s heard that blacks can be cowboys; otherwise, the other non-blood brothers Douglas (Zak Orth), Cole (Justin Chambers) and Travis (Tristan Tait) fail to establish much individuality. They do pick up distressed Annie (Kristin Griffin), supposedly now part of the family but actually cook and housekeeper. Grown Mary Rose (Jennifer Garner), protected from life by her adoptive brothers, doesn’t develop much personality. She falls for the first attractive gent, John Stringer (David Newsom), but he’s not a wise choice. Scotsman Fergus Carroll (Casey Siemaszko) moves onto the range where Adam’s dreamhouse is under way and to work with a cattle station, and he falls for bland-but-pretty Mary Rose, who’s got googly eyes only for Stringer. One brother dies fighting cattle rustlers, but even that doesn’t have much of a charge. Mary Rose heads East to find her lineage and ends up well off. Stuart Wilson’s her urbane and dull papa. Vanya Rose, appearing in early and later portions of the vidpic, is the cause of Mary Rose’s lifelong predicament; she hands the production a welcome hint of mystery. Cain finds little excitement in the stolid story, and Garner’s Mary Rose is unexciting. Monique Prudhomme’s costumes are good, and Willy Kurant’s lensing and Sabrina Plisco-Morris’ editing are OK. John Willett’s vidpic look is Western familiar, though the NYC scenes are solid. Steve Dorff’s score is a gentle reminder that time’s passing.
