Signs
I personally think this is M. Nights undisputed masterpiece. It is terrifying, emotional, and unorthodox with its comedy. All tied together with its chilling score (which feels like an additional character in the film).
Ever since I was a kid, this movie has had such an impact on me and still to this day it gives me wicked goosebumps and can easily get me worked up with Mel Gibsons performance.
To hell with the “water haters”, I love the message behind this and everything about its strain.
Such an interesting use of the alien invasion genre, and an effective family drama about restoring one’s faith.
