Signs (Mel Gibson)

Just saw it again for the first time since it opened, and I'd forgotten how many outright belly laughs there were. Abigail Breslin's little girl had some of the best (not to mention the tin foil/Hershey's Kisses hats). I really enjoyed it; BUT in retrospect there were many nonsensical main plot points. First, even in the unlikely event they were ignorant of their Wicked Witch water allergy, it seems unlikely they'd invade a world without determining thru their scouts if the atmosphere, microbes and other things were dangerous. The upshot is a kid with a squirt gun coulda kicked ass. A good rain storm would wipe them out. So why invade a deathtrap? Also, these guys had no sense of survival planning. The boy didn't have his inhaler - the first thing a parent would think of. The cellar, their last resort, was not stocked with water, etc . And most of all, what rural guy in such a situation, regardless of his prior beliefs, wouldn't stock up on guns and ammo? I mean, you gotta defend your family. Even if they didn't melt when wet, these had to be the weakest, half-assed alien invaders ever. They literally couldn't fight there way out of a locked pantry, were unarmed and unarmored (and no rainsuits!), and who couldn't even take a man with a baseball bat. What would they've done against a battalion of marines (especially with super-soakers). Pretty weak stuff.
