Yeah, M Night Shamalayan.... or however you spell it. Hes in all of his movies.

Anyway with the water thing...I don't think it was water that killed them. Yes, there was a reaction to the water, but I don't think this was fatal to them.

Remember on the TV it says something like "The fight started to turn around in the Middle East where 3 cities found an ancient ritual which was fatal to the invaders." If water was the main posion, why wouldn't they just say "Go get some friggin water guns and start shooting the bastards." You don't hear this at all in the movie.

You could probably compare the aliens to humans. The're probably susceptable to injuries, just like us. Perhaps water to them is like some type of gas or acid to us. I know there are a lot of plot holes in this one, but I think i can overlook the and try to have fun with the movie.
