I have never written a screenplay in my life. This is more of a exploration hobby. And if my screenplay gets made, great! If not, that's okay too.
Overall, the reading and flow of the script would be A LOT better if you cut back on the description on a lot of items. Call a gun a gun, an airplane an airplane, and so on. Be general in those specifics, because almost no one is going to know one type of gun is from another type of gun. That will, and did slow down the reading. I know that I already mentioned it earlier but, I feel that it needs to be addressed and is hurting your script. This intention is to better your script. That said, it is still a suggestion, do with it what you will. Good luck on your future drafts!
Overall, the story and character of Carl was bittersweet. He was just an average guy with an average job, but when his liver goes out, you find out all of this other stuff about him as a person right before the end. The fact that it ended right before we realize it and wanted to see what happens next with him and everything else, is what made it that way. It was over before it begun. I think there is room for improvement here, only if you choose to.
It reads very similar to the first one in terms of action scenes and gore violence. It is still an all out slugfest. And even the characters mention that as well. Zombiathan was by far the most sinister, Victor with his wit and banter with everyone else in the screenplay. Ice Reaper is somewhere in between. Killing off the Mayor in the manner that it was not only got rid him, but will use his death to add more depth to SVF and Veronica. As stated before it reading like the first one is where it is lacking. Probably upping the stakes with SVF and Veronica's pregnancy out of the gate might do that so SVF would be constantly worrying about her and her unborn child's safety might help. It might add more of a human side to him as well. Yet, this is a trilogy, and I'm sure you have ideas to wrap this up nicely in the end, which for obvious reasons I'm not seeing because there's one screenplay more left.
