《谍影重重4》虽然导演换了，马特｀达蒙也不知去向了，取而代之的是潮流帅哥杰瑞米｀雷纳扮演的亚伦｀克洛斯特工，他在《碟中碟4》中扮演的跳下巨大风扇旋转的深井中的特工形象至今还在我的眼前；但整体内容仍然由CIA主导，“绊脚石”计划为主线，追杀特工为全部，一层不变的永远的超级个人英雄主义，外加意外收获的纯美的爱情故事。
整部电影在开头阶段以复杂而眩目的方式在美国、首尔、菲律宾等各个国家和地区之间变幻镜头；CIA人员各个忧心忡忡、一副祸事临头的样子；而硬汉装扮的男主角亚伦｀克洛斯身处白雪皑皑的山峦之中，一会儿在冰冻刺骨的河中潜水，一会射杀彪悍的狼群，一会儿又飞跃深不可测的峡谷，神秘的就是他时不时的从自己身体抽一管血放在专用的盒子内，然后再吃上一个蓝色和一个绿色药片。故事在这个时候似乎是复杂的、曲折的，但可惜的是或许这就叫做故弄玄虚。很快一切都明了，CIA主导的一项人体试验计划宣布失败，为了保住他们的声誉，唯有除掉参与试验的医生和试吃药片的所有特工之外，别无选择，注定的结果是亚伦｀克洛斯活下来了，然后追杀他便是整部电影的全部。
在《碟4》里，这位英雄与我们熟知的好莱坞缔造的英雄几无二致，聪明、机敏、体力超群，但是影片告诉我们这是吃了药片基因被修改的结果，他要么继续吃这种药维持现状，要么大脑停止运转立即死去，唯一可能的解决之道就是让参与实验的医生为他注射活体疫苗修复已经被修改的基因，但这也是成功概率极低的方法，于是美女博士马塔｀谢林顺理成章的出现，成为亚伦的搭档，最后英雄恢复了健康，真是奇迹，被修改了DNA都无法击败的英雄，恐怕历史上还仅有此一个。
碧海蓝天、阳光、木船、微风和远处飘渺的海上风光，外加摇滚乐，坐在身边纯真可人的美女，他们在菲律宾海域摆脱了逃亡，这样美好的结局，说什么好呢？看来得感谢一下残忍的中情局，不可理喻的拿自己的特工做人体实验，再杀死他们，还得感谢绵软无能的菲律宾警察，外加打扮酷毙的灰太狼般死缠烂打追击亚伦的韩国特工。
值得一提的还是那首片尾曲《extreme ways》，依旧充满了孤独、无奈、凄楚和自我。
extreme ways are back again
extreme places i didn't know
I broke everything new again
everything that i'd owned
i threw it out the windows, came along
extreme ways i know, will part
the colors of my sea
perfect color me
extreme ways that help me
they help me out late at night
extreme places i had gone
but never seen any light
dirty basements, dirty noise
dirty places coming through
extreme worlds alone
did you ever like it planned
i would stand in line for this
there's always room in life for this
oh baby, oh baby
then it fell apart, fell apart
oh baby, oh baby
then it fell apart, it fell apart
oh baby, oh baby
then it fell apart, it fell apart
oh baby, oh baby
like it always does, always does
extreme songs that told me
they helped me down every night
i didn't have much to say
i didn't get above the light
i closed my eyes and closed myself
and closed my world and never opened
up to anything
that could get me along
i had to close down everything
i had to close down my mind
too many things to cover me
too much can make me blind
i've seen so much in so many places
so many heartaches, so many faces
so many dirty things
you couldn't believe
i would stand in line for this
it's always good in life for this
oh baby, oh baby
then it fell apart, fell apart
oh baby, oh baby
then it fell apart, it fell apart
oh baby, oh baby
then it fell apart, it fell apart
oh baby, oh baby
like it always does, always does
