The new cut looks good! Much cleaner in the beginning with less text. I think you could even simplify it a little more. Start out black screen, a little ambient noise, birds chirping – fade in “The disease had become an epidemic. The CDC couldn’t cure it, hell, they couldn’t even contain it in their own facilities.”

Leave that up there just long enough to read and then bring in the “Corey!” scream – cut to walking through the woods.
