The aliens in Signs are idiots for invading a planet that’s 70% water. And if they landed in a cornfield in rural PA in the middle of summer the humidity would have killed them instantly.

And what’s worse is Shyamalan lives in PA and should know this.

Lol I actually grew up near where the movie took place and now I feel stupid for never thinking about the humidity factor. Summer in PA is underestimated by those who think “it’s the northeastern US, how bad can it get?”. For those of you who don’t know, most summer days you can see the humidity and you’re drenched in sweat about 2 minutes after you exit a cool shower.
