I love the look of fog, but never breath the stuff anymore. Very bad for your lungs. Rule to follow is:
Never breath any air you can see!
I used to love the horror movies back in the day, usually foreign, that had lots of fog added for spooky effect. I cared more for the movie’s atmosphere than the dialog and certainly like shadows and fog much more that buckets of blood, which by the way I think is the name of a horror movie. The Fog was very eerie movie made in the 1980’s very well done. I believe they did a remake years later which I have never bothered to see. I have never seen a remake yet that I have remotely enjoyed. They muck them up with so much needless gore that it’s just a waste of time to those not of a serial killer nature.
