不要深究剧情还是可以一看，有漏洞但也不是无脑片。坎通纳还挺适合演警探，说实话女主真是不容易。。。
剧情确实挺狗血的
坎通纳真不适合演这个。。。
荒谬透顶
因为常露点就算是喜剧嘛？？？
平时就锻炼身体超必要啊
超人和蜘蛛人变身还需要脱衣服，女主角说变就变，也太快了吧~
坎通纳···
纯为国王打分
法国人喜欢用dna说事 以前的暗流也是 写简介的 到底有没有看过片子啊 唉
大bug！
精彩的2点，让人忘记那无语的2b剧情设定。
真不赖。这个主题以前从没有过，很新颖。过程也很紧张，就是有点烂尾，没有解释好为什么女变态要这样做，没有父亲神马的解释弱暴了。女主象张静初。我爸本来还想换屋呢现在不敢换了
莫要看这个片子的分数低。。其实真的挺不错。
这电影有被美国翻拍的可能
