The dumbest aliens ever, that's who! You don't invade a planet that is 2/3 submerged in a caustic fluid, and the other third is pockmarked by puddles, lakes and streams and badgered by frequent rains and snows. And where every single sentient inhabitant makes sure to have a supply of the stuff at the ready on a moment's notice. At the most you set up embassies somewhere in the desert and ask the inhabitants not to bring any HELLJUICE in with them when they visit. And you wear Protective gear whenever you engage the natives on their own turf. You do NOT pick a fight with them whilst completely naked. That's just bad practice. Have they never fried bacon???
I was actually really uplifted when I saw Signs. The movie gave me chills, but inspired me to pray and I slept just fine that night.
The Forgotten with julie whatsername... julianne moore I think. That movie was scarier to me. At one point in the movie I jumped out of my seat and used loud profanity, it frightened me so bad.
I did NOT sleep very well that night.
