The live action nailed it! Sure there are some cut scenes from the anime but the important details were not left out. The whole movie can stand alone and even those who haven't seen the anime yet could surely understand the whole plot. The characters' acting are spot on. Takeru Satoh's (Nagai) portrayal is effortless. It is so natural and convincing. Sure, there are times when I wished he'd say "amakakeru ryu no hirameki" but that is only because I was so affected by Gou Ayano's (Sato) acting as a villain I wanted him to be dead for sure but this is Ajin; Die and be alive. Gou wcompleted the ambiance of the movie. To sum it up, everything, from characters to the plot were all stitched perfectly I could not ask for a better adaptation.

I didn't have high expectations going into this and this point is important for my review.

I've seen both the first and second seasons of the anime. What the movie here does essentially is cram the entire first season into 5 minutes and then proceeds to mashing up season 2 in a spectacular mess indeed.

Firstly, the changes that they brought were a combination of very poor decisions. There is no airplane crashing into a building instead it's a building collapsing into the other building <- This is much better in my opinion.

Nagai's sister is NOT supposed to be out of the hospital for a very very long time. It takes almost the entirety of the second anime season for that to happen and it happens much better. Not a group of extras who can't act showing up at grandma's door but Nagai rescuing her from an angry mob at the hospital. Plus a dramatic entrance by Nagai's best friend who was completely omitted from the film.

I also did not like the changes to Nagai's character. I thought he was just fine being a high school student, university freshman would have worked as well. He spends most of the anime deciding whether to help at all or not. But in the movie, he makes that decision pretty quickly therefore character development is lost.

The acting as expected from a Japanese film was pretty weak, superficial and fake. Save from a few decent performances, Satou's and Tozaki's, the rest were close to abysmal.

Overall, do not waste your 1h40 or whatever it ran for and watch the anime instead.

This film essentially revolves around a special type of human known as "Ajin" who have the ability to regenerate back to life after being killed. So in that context they are basically indestructible super-humans. Although this is a relatively new discovery the news of their existence has become known throughout the world but the fact that they are so few in number doesn't especially alarm anyone in particular. It does, however, fascinate some scientists in Japan who then covertly capture one by the name of "Kei Nagai" (Takeru Satoh) and proceed to brutally experiment on him in a most sadistic manner. However, when news of this is leaked to a leading member of the Ajin species named "Sato" (Go Ayano) he immediately takes matters into his own hands and frees Kei through extremely violent methods. Upon doing so, however, he becomes very displeased to learn that Kei doesn't share his psychotic feelings towards other human beings and the two of them become locked in a fight to the death-if that is even possible-from that point on. Now rather than reveal any more I will just say that I was extremely disappointed in this film in that it was nothing more than a series of almost identical actions scenes repeated over and over and over again. There was no real plot, no substantive character development, a superficial script and the acting was rather poor as well. In short, it was all action and CGI. That being said, while this movie might satisfy some viewers who put a high premium on films of this type, I found it to be almost excruciating to watch and I have rated it accordingly.
