This movie was one of the worst I've ever seen:
1) The central character is totally unsympathetic with no opportunity for redemption.
2) Sandler's role is one-dimensional and a caricature of his normally frenetic acting.
3) The plot is poorly constructed and the opening scene makes you think the movie is initially about the abuse of diamond miners in South Africa.
The only thing I liked about the movie was the surprisingly solid acting of Kevin Garnett, the professional basketball player.
Stay away or be prepared to walk out.
