Wow you guys sure are picky.
I really liked Signs, I loved the characters and how everything game together at the end. Great ending too.
About the water thing: Could have been milk for all I cared. He used water because it helped "tie everything together" because the little girl left water glasses everywhere, perfect for the family to kill the alien.
I love unbreakable too. It's like real life superheroes. I think you either love or hate his movies. And from what I've heard people either loved or hate The Village, so I'll probably love it lol.
