The action in this movie was absolutely incredible but I missed some deeper character moments. Like...

Were the Ajin truly colder than humans? What happened to Kei and Eriko's parents? Why did Izumi work for Tosaki and the department that experimented on Ajins when she was an Ajin herself, how could she have just stood by and watched them do that to people like her? Etc. etc...

I think my favorite moments were the back-n-forths between Nagai Kei and Satou because Satou was a fantastic villain, deranged, sure, but you got where he was coming from and why he was so gung-ho about killing humans. Their scenes were the best part of the movie.

And then the scene at the end, when Tosaki betrayed Kei. Did he actually feel regret? We didn't really find out anything about Tosaki's motives so it was hard to say for sure but... did he feel regret about betraying Kei after everything he had done for them? It sure looked so but, well, he was as disgusting as everyone else who participated in those experiments, Izumi included, so... ¯\_(ツ)_/¯

But honestly? I was glad that both Kei and Satou escaped at the end. I usually like for the bad guys to get what they deserve but here...
