This Disney-produced "based on the inspirational true story" sports flick is pure formula. But it's a formula that works. Kevin Costner is a high school coach exiled to a dirtwater farming community in California. There, he creates a winning cross country running team with some of the ragtag local migrant worker kids. It's all very familiar, but director Niki Caro (Whale Rider) shows considerable sympathy to the impoverished farm workers depicted here.129 minutes PG.
