I remember jumping in my seat in the theater

I had this whole theory built up about how the aliens were manifestations of the little girl's trauma and grief and everything was just happening within the town. All the stuff on the radio and TV was her using spooky kid mind powers unconsciously. That's why they were allergic to water: she has a weird thing about contaminated water glasses.

And then at the end he just hits the fucking alien with a baseball bat and the credits roll. What the actual hell.

That's how M. Night Shyamalan movies work! Don't think too much!

Honestly, signs was the first movie I ever experienced terror from all the way up until the end and now I literally do not give a single fuck about that movie.

Turns out I have a fear of aliens walking in the distance. Or, well, had.

Signs both clarified and cured me of it at the same time.
