This must be the first in my life I've ever seen relatable and fragile characters as the protagonists of this type of movie, usually relegated to kickass one-liners spewing macho men or women a là Doom Guy or Ellen Ripley (funny, considered this movie was clearly influenced by Alien and Invasion of the Body Snatchers). For that alone, this movie gets 1000% my approval. Hollywood and America please take notes...once again.
