我是在巴望着结尾能有个爆点的焦躁心情中度过的，结果木有，那就是烂片，既不搞笑也不感动，眯眯眼的韩智慧和金鱼眼的李东健是拍完这部空洞乏味的电影后分手的吧？
oh come on 别闹了
当时引起不少争议，只因为说B型血的人怎样怎样，好无聊。这是炒作吧？
大学的小电影院连场看的，封建迷信害死人
N年前的屁事
因为B型 所以喜欢
你的长处就是给自己找到借口
昨天在CCAV6看了一会儿，太扯了，血型哪有这么重要啊，这俩人的性格问题根本就是自己的问题，表随便赖到血型头上
同B型
为什么韩国女的总是装纯啊
可惜了，曾经的银屏情侣啊，《b型男友》《18岁新娘》如今形同陌路
这两人可惜了，多好的一对儿啊
看在韩智慧的份上..
RicSung为什么要一起去看这部电影？仅仅因为文兔子是B型血？
冲着大叔去的，但是不好看
