I was shocked when I read the script that was leaked. I thought Shane Black was supposed to be some kind of script writing wunderkind. The script was just awful, forget about the changes made to the lore, it was just a terrible script. The scene where the general was explaining the "emmisary" Preds...sounded like some 16 year old Predator fanboy trying to argue why his oc Predator should be the star of the next movie.
"Ok...they're, like, the good Predators, but they're still Predators man, so they're like still super badasses and kill prople and shit. It's, like, all morally GREY and shit, bro! Like Game of Thrones, bro!"
Only instead of calling the guy a moron Fox gave him 88 million dollars to film his fanfic.
