Them 2 happens to be my favourite movies.
I just love those flicks where you are leaving the cinema thinking and pondering back and forth about what really happened, how and why. So are there any movies within the same genre? I'd love to watch some quality flocks next weekend when I have lots of time off! :)
Both movies mentioned above are also school examples of how you create an eerie, yet warm atmosphere.
Now that's art.
