Review: There isn't a whole lot going on in this story -- just two men employing very different ways of handling memories of Vietnam. But what it lacks in premise, it more than makes up for in acting and realism. It's a quiet film about the bonds of friendship and shared experience. We even get romance (not gratuitous -- just another very real piece of this story). It's well worth seeing. Question: is it a positive review?
yes
