If Yelp existed in the '60s, our main character Richard Perry would have given the entire country of Vietnam zero stars.
You can't really blame him, though, because all of his Vietnam experiences are colored by the war. Either he's on the safe ground of the American base, which is hot and full of rats, or he's on a mission or on patrol, where he could in theory get killed at any moment.
But even though Perry mentions the rain or the mud more than anything else in Vietnam, he still realizes that its people are a lot like him. Even though they are his enemy, he has more than a few moments of recognition—including when he kills a member of the Vietcong.
