Went and saw Signs this morning.
M. Night Shyamalan is a fine storyteller. As a study of how to tell a story well, Signs is as good an example as any movie. Joaquin Phoenix turns in a great performance full of life, humor, and realism. Mel Gibson, father of seven (!) in real life, is a completely believable parent.
That’s the good.
Now, I think anyone who knows me knows that I can suspend my disbelief above some pretty good-sized logic holes for the sake of a story — it doesn’t bother me, for example, that they don’t explain how the big critters in Pitch Black can fly (they certainly couldn’t on Earth) — they obviously can fly (since they do it all through the movie) and explaining it isn’t important to the story — it might satisfy some of my geeky curiosity, but it’s of no real import. Logic holes up to a certain size don’t really bother me.
Signs, certainly a finely-told story, is, substantively, nothing but Hole.
Let me put that more clearly: certain plot points imply things that are simply too ridiculous to ignore.
Spoilers below.
Tips for Aliens Intent on Attacking Another Planet:
1. If 70% of the target planet is covered in a substance that melts your skin off and precipitation of said substance is common, wear protective clothing. Presumably, since you are a spacefaring race, you have the ability to construct clothing that will keep you dry.
If you cannot create such clothing, reconsider the invasion.
2. As a spacefaring race set on invasion, it behooves you to arrive with:
- Weapons.
- Clothing of any kind at all.
- Tools that would, at the very least, allow you to breach a pantry door.
If a building that you target with your full offensive ability is left looking as though it suffered nothing worse than household burglary and minor vandalism, reconsider the invasion.
3. If water melts you, you might want to rethink your abduction policy. It is not in your best interests (or believable) to abduct creatures (humans) that are 90% water… they will not make a good snack for someone of your physiology. If you are abducting them for study, consider using less than 400 ships hovering over all major cities — stealth is your ally.
(Another thought: Perhaps they weren’t taking people for food or observation… maybe they just needed clothes.)
If every living thing on the planet is mostly made up of a substance that is pure acid to you, reconsider the invasion. Whoever suggested this world as your next target might have been joking.
In short, M. Night needed an otherworldly threat that would arrive, be utterly terrifying, and then leave after one night. It is my opinion that he should have chosen anything at all but technologically superior aliens (they do have space flight*) that inexplicably attack the Earth nude and unarmed. (If they weren’t nude, see Tip #1.)
* - Maybe they don’t have Faster than Light travel, though… it might be that they arrived in generation ships and they’ve been in space so long that they’ve devolved… the automated systems did the landing?
The parts of the story that work (the exploration of faith in the face of misfortune and uncertainty) work very well. The parts that don’t work… really don’t work.
