Aliens Are Morons

I need to preface this by saying that I'm a huge fan of alien fiction, be it movies, books, or those hokey shows about alien abduction. The X-Files blew my mind in the 90's.

Having said that, I have to ask... why are the aliens in movies always completely stupid?

Take the movie Signs, for example. These aliens have mastered the ability of interstellar travel, yet they plan to attack Earth, a planet comprised of vast amounts of water, which just so happens to be poison to them. It literally reacts like acid on their skin. In preparation for this, they wear these amazing suits that keep water out so they can be protected.

Oh wait, no they don't. These morons run around naked, completely vulnerable to the devastating effects of a child with a squirt gun. What if it rains? So, the fire department is now mankind's best weapon? Genius.

I especially liked that they spent a few days climbing on the roof and running through the cornfield like a couple of pedophiles spying on a slumber party.

The Tall One and I watched an alien abduction movie last night that had the dumbest space travelers ever in it. They've conquered space and time, but if you hide in the basement, they're totally fucked. Weapons? Who needs them when we can just chase you through the woods. They beamed a few people into the mothership with ease, but god help them if you sneak into the barn. Those doors are made of wood, dude! There's no way they can get through those.

The other thing that I fail to understand in these movies, is why aren't the people abducted from the beginning? In most of these, a family, or friends, whatever, are hounded throughout the movie. They hear sounds, see bright lights, feel a nearby presence, and then they're finally abducted at the end.

Do aliens have a sick sense of humor? They like screwing with people? Why spend days dicking around?

Aliens are teases, apparently. And stupid.
