This movie could have so much potential. So much. Being Snyder fan, I was waiting to watch this one. I know he is one for details in his movies (JL Snyder cut) but he left so many loopholes. [Spoilers ahead]
There was no storyline for Geeta. He could have easily edited that part out.
Alpha was making more like him so alpha (or betas) of the sort, that has brain and what not?
The female alpha was pregnant while being a zombie, how?
After nuke attack, that van guy was out in radioactive atmosphere? He was locked inside safe, how was he able to get out?
It has its good parts - all the zombie fights were filmed spectacularly but story dropped it's charm several times.
