Just wack... The mental gymnastics he goes through to make a bad movie is wild. Like you you give Zack a home run concept...
Zombie Heist / Escape from Las Vegas concept Movie and he just finds a way to shyt all over it.
Zombie robots, zombie fetus, zombie society /politics, stupid dad daughter drama, kill off every character but one, turning Zombie into Bio-Weapons, focal blur, and every stupid inconvenience that's there to get to next story beat.
Like damn... Maybe James Gunn can save this franchise, because this seems up his alley. It is unfortunate they wasted the Zombie Heist film with only 20 minutes of a fake Heist that doesn't make sense, because Zack had to write in another inconveniences with the bum ass tiny helicopter
