Well done Mr. Spielberg. Another enormous budget movie, well made, but for children

Rating: 5/10 (7 December 2005)

The movie is good entertainment.
Contains spoiler!
Although it begins very interesting, the effects are great, the revealed secret is not such a big deal.
Am I the only one who wondered how come a superior race, which planned the extermination of the human race 1 million years ago and buried their destruction machines underground, on Earth, "forgot" to test the environment on Earth so they would be able to survive when attacking? And with such superior machines, untouchable by man, while in middle of annihilation the bad guys (the aliens) suddenly get ill and die because they couldn't adapt to the environment on Earth?!
It might have been believable in 1930 but today it's at least silly...
I was expecting something else from this movie, considering the beginning, the story.
