After watching the anime, I can say that the film is pretty much scene for scene taken from the first season. Some details were slightly changed, some scenes removed, which kind of takes away from the smartness of the story, but what can you do in just two hours. And it feels like it was actually adapted from the anime, not the manga, even if it adds some elements that are relevant only to the rest of the story.

That being said, what the hell were those wigs?! All the "children" were wearing wigs that just looked plastered on their heads. You could have just used normal hair, ffs! There is nothing wrong with "recasting" the hair.

Bottom line: same story, but a bit lackluster. I recommend just watching the first season of the anime and stop there.

Ok, so usually live action anime adaptations are pretty forgettable, but i would say this one was actually a bit above average for its genre. They did make a couple changes to the anime (which i will get to in a moment) and some were good, others werent. For example, emma and norman find out that the transmitters are in their ears pretty much instantly in this version without having to investigate to figure it out, there was also this new scene where korone was about to find the transmitter destroyer, and to its credit it was actually pretty tense. Now the acting was mostly pretty good from what i can tell (i dont speak japanese so i couldnt tell you for sure) they had to age up the characters from 12 to 15 in this version, probably because they couldnt find any decent 12 year old actors to play the part. Then again the actor for phil was also decent so i think they probably could have done it without changing the characters ages if they looked hard enough. Korones acting was pretty over the top though, i mean even ignoring the fact that they got a white actor to portray her, she was way too over the top with her preformance. Also the movie had a few weird editing tricks, liek in one scene where korone was walking towards the kids and the director thought it would be a good idea to comically speed up the footage of her walking, it looked really goofy. The demons actually looked pretty good in the movie, they werent seen very often but when we did they looked pretty real. They were animated with CGI and the way they physically interacted with the humans looked convincing.

So yeah, the movie actually ended up being not terrible, if youre a fan of the anime or the manga i would say maybe give this a try, you might like it.
