I didn't see anything abnormal about the preview. Cultures are different, what we may find stupid the Japanese may find heartbreaking. Recently, my friend's boss was told she had 2 weeks to live and died two days later. We weren't even sure if her daughter, who lives in another state, got home into to see her mother before she died. So there's no telling how people would react to such news. Does crying in the ocean seem a little over dramatic? Maybe. But there's no telling what different people do when faced with certain death. I'm not getting on the people criticizing that scene, just expressing my views on it.
