Saddle up for a one-way ticket to inspirationville: this Sundance-wowing documentary gives an insight into the real-life horse whisperer, child abuse backstory and all. Buck Brannaman is the sort of copper-bottomed authentic that makes you wonder how you ever swallowed Robert Redford's blow-dried impression. Half nag, all guru, he burrs wise words about wrangling men and beasts, one's primal nature and one's animal altruism. Yet he's also acid enough to balance out the slight tang of treacle in Meehl's treatment. There's a whole heap of Americana to wallow in here, but it's testimony to the director and subject that Buck still trots along at such a lick. Catherine Shoard
