This might be the worst movie I have ever watched lol. Terrible graphics, horrible acting. They run into some acid mist, and hide in a cave. Apparently mist is scared of caves and can't go into a gaping hole lol.......the actors can't even cough realistically ahahaha. And for some reason this group seems to be maybe the last people on earth. Set looked like the Walking Dead, cars all over the place lol.
