以下幾段是引用imdb老外的回應，深感略同
引用:
They're smart enough to build these monstrous craft but not smart enough to build leak-free suits (or any suits for that matter) in case there's some icky bugs that might kill them? Brilliant!
聰明、高科技到可以做出這麼大的武器，卻做不出可防漏的衣服？？
地球人上太空，都懂得做層層防護的太空衣了說，再說地球人還有生化防護衣呢！
這些比地球人更高明的外星人呢？不合邏輯吧
地球人不是一直被監視著嗎？應該知道人都在哪？ 怎麼一出現還要到處找人？
科技既然比地球人厲害，怎殺人還需這麼費力，沒有比氫彈更具毀滅性的武器了嗎？還能漏掉阿湯哥
導演把外星人表現的太愚蠢了，衷於原著但不符合現代科技水準
強力閃電由天而降，但在此之後，天上就沒有什麼可怕的武器下來，都是從地下上來
什麼原因誘使火星人開戰，沒有說明？什麼東西在雲層之上，沒有交代

all electricity is gone, yet one guy is using his camcorder ...
Tripod出現時，所有電器用品都不能用了，阿湯哥的錶也不能，但....怎有人還拿著DV在拍外星人的武器？？
引用:
The movie does have some great effects but the storyline is seriously lacking. The part of the movie that left me feeling cheated is the end. We have just seen the destruction of millions of humans, but Cruise is able to make it to Boston, a large city, where the streets are deserted. We focus in on a row of Brownstones where a single family emerges. The family looks as if they are about to go to a wedding. Everyone is clean, well dressed, and Tom Cruise's ex-mother-in-law looks like she just had a manicure. We are supposed to believe that after this horrible attack, this one family is unscathed and reunited in a major city? Don't be ridiculous.
有不少老外也是覺得結尾太過草率
劇情邏輯瑕疵過多，沒有新意
我想我對導演期望過高，所以也就失望了
