Logic is so completely absent it's ridiculous. This is the "twist:"

Rating: Null/10 (13 March 2012)

So it turns out the yes, aliens are invading Planet Earth.
They land, you essentially never see them or hear about them doing anything except for a shot of one passing in front of bushes at a kid's birthday party.
Then they go home, after annoying people for no apparent reason.
Oh, and they're just people in dark green green suits.
Why did they come? Nobody knows, and really in the end, nobody cares. Because these have to be the dumbest aliens in the galaxy.
Why did they leave so abruptly? Because water is poisonous to them. Yeah. They crossed interstellar distances to invade a planet whose surface alone is 70%+ covered in a substance that is toxic to them. So what about the oceans and lakes? Or taking slaves that are mostly water, or food that is based on water...
... what's next, the Human Race invades Venus and is shocked to find out that the clouds and raining sulfuric acid aren't conducive to colonization? Because that would be the equivalent.
This is a terrible movie with a twist fit only for people who watch movies without asking questions of the obvious. I don't know why people keep buying the guy's scripts.
"War of the Worlds" was brilliant for its time. Germs had just been discovered. It made sense for the time period. But aliens who can cross the stars to invade a world toxic to them? Did they never develop the science of simple spectroscopy? Don't see this movie. Take a sharp blow to the head first. Ask someone else about the medical reality of a woman being cut in half but able to survive until her husband has to make the hard choice of pulling the F-150 off of her.
