Excellent action flick that suffers from a condensed running time
18 July 2019 | by grandmastersikSee all my reviews

I haven't read the comics or seen the cartoons, so I went into this clueless - no idea what it was about whatsoever.

The lead, Nagai, is in hell: he is experimented on, he has limbs amputated, he is killed and... he comes back to life again, fully healed. This torment goes on and on - and this being the film's opening, we don't know how long he's suffered this cruelty.

Sato is another Ajin - which is what Nagai also is, hence the never-ending cycle of death and life; he busts Nagai free, gleefully slaughtering everyone involved in the experiment and asks Nagai to join his crusade of bringing down such evil facilities, so their kind will never again endure these ordeals. The catch? Sato wants Nagai to kill a few scientists to prove his loyalty.

Okay, so after going through hell, why not get some payback? Nagai refuses and illogically fights Sato to save those who had butchered him relentlessly... seemingly for chuckles. This is the first head-scratching moment in a streamlined film which skips the majority of character development to concentrate on the action. And why not?

The problem is that, by condensing - good only knows how many - comics into something like 80 minutes (which is actually 109, but it goes so fast!), Nagai's character and his bizarre choices don't make a great deal of sense - a massive pity, because the action's great and there are a lot of cool ideas to more than make up for a lack of Hollywood production money.

Ultimately, the decision to cut 10 or 20 minutes by omitting the reasoning behind Nagai's stupidity/irrationality (take your pick), along with that of a certain female, hurt the film much more than slowing the tempo slightly or pushing it over 2 hours ever could. This film easily could've been a 9/10 but as it is, a 6 is fair and a 7 generous - and since I liked the concept so much, I'm being generous.
