In general I never cared much about scary movies, but there is ONE SCENE (in an otherwise crappy movie) that left a strong impression on me.

In the movie "Signs", there's a moment when the news are showing footage from an alien sighting in Brazil. Usually, whenever a US movie tries to depict another country or culture, it ends up being so poorly done it's almost like a caricature. But not this one...

The scene is from a birthday party, and every little detail is so authentic that, as a Brazilian, it's immediately obvious that it was actually recorded in Brazil, at someone's actual house.

It's shaky footage from a camcorder (remember those?). There's the party decorations, the kids' hats, the car outside, the voices (which are intelligible Brazilian Portuguese, not gibberish). Everything felt so real and familiar, I could swear I have been in that exact party at some point in my life. And then the alien shows up and HOLY SHIT did that scare me!
