1、“背包客文化”——现实的出走和意义的寻找
从电影原著小说the beach的简介中可以提取出几个关键词：“背包客”、“旅游业”、“背包客社区”。（it is the story of a young backpacker's search for a legendary, idyllic and isolated beach untouched by tourism, and his time there in its small, international community of backpackers. ）
“My name is Richard. So what else do you need to know? Stuff about my family, or where I'm from? None of that matters. Not once you cross the ocean and cut yourself loose, looking for something more beautiful, something more exciting and yes, I admit, something more dangerous.”
开场白即表明了Richard对背景的抛弃——放弃一切去寻找一个他也不知道是什么的东西，总之就是不同于现实的、美好的、不这么“平庸”的东西。
“There is a beach, understand? it is too beautiful, too much ample too much sensation, I try to forget but I can't control it. She is on an island, the island is a real perfection I am just talking but that's nice. it is totally secure totally forbidden, nobody can ever go down. A few people went there once upon a time, people with ideal, not normal tourists, fucking （瘪三）"
第一次对于the beach的描述来自达菲，他对于海滩的描述是”完美的”、“禁地”，对于他们自己的定位是“有理想”、“不同于一般观光客的”；但是他突然又说 “有理想哈？他们都是寄生虫！贪婪又愚蠢！”，说他为了保护海滩，让他的朋友们离开，但是他们不肯听从。
"I just want to leave again. I understand more clearly that why we are so special, why we should keep the secret, or sooner or later, they will turn it into this. Cancers, parasites, eating up the whole fucking world."
去主岛换米再次强调对现实生活的厌恶。而且现实生活是“越来越糟”。
