7. If The Aliens Are Allergic To Water, Why Do They Invade A Planet That's 70% Ocean?

Why M. Night? Why? I'd hate to be the first to question alien logic because... well they're aliens and who knows what they think but their masterplan in Signs does seem a little bone-idol. If you dissolve in water, I cannot comprehend why you'd want to invade the Earth. We're just a soggy wet ball hanging in Space! Its not even like they'd have to look very far to find a more suitable environment. Look to your right Alien thing... you'll see a big red ball of dust I'm sure you'd be a lot more comfortable living on. As a result of this bizarre invasion plan, Signs loses a little credibility. It starts off so well, with the first Alien sighting coming at a child's birthday party in Suburbia - a masterstroke of suspense and genuine horror, from the director of the Sixth Sense. Alas, it falls apart when the bad guys find the one house in America that happens to have a thousand glasses of water hanging about the place. It screams lazy writing and a lack of ideas and does a good job of ruining the film. Still, it could have been worse, the aliens could have tried invading England. Good luck getting off your spaceship without a brolly folks!
