"Diamond Men" is a slice-of-life flick about an aging traveling diamond salesman (Forster), his protege (Wahlberg), and their experiences on the road. In spite of being a good natured light drama with a heart, "Diamond Men" can't escape its amateurish screen play and obvious low budgetness as it wanders through fields of pure corn all the way to its feel good conclusion. A mildly enjoyable B-flick which should be an okay sofa spud watch if it makes it to broadcast. (C)
