Honestly, it's an _alright_ adaptation, there's way worse out there (like Netflix's Death Note for example), but you should just watch the anime instead of this movie, almost everything in the anime is better. Except for the soundtracks.
Now, for the actual review of this movie:
It misses too many aspects of the anime, it rushes them, it applies things from the anime that are purposefully developed, but without developing them in the movie. Ichiro Inuyashiki should care way more about the lives of the people he couldn't save, but in this movie, he doesn't care enough. The whole reason why he wants to save people is because it allows him to "stay human", even as a robot, it allows him to find his humanity again, but in the movie, it's not that clear why he saves them in the first place.
The CGi itself is REALLY good though, way better than the CG which was used in the anime. It's really good CGI which won't take you out of the movie.
Action scenes are also good, they were satisfying to watch.
The soundtracks are also good, maybe better than the ones in the anime, except for one thing. The song used in the trailer isn't used a single time in the movie, except during the credits, which is really dumb as it was a song by MAN WITH A MISSION, the band who did the opening of the anime.
Anyway, overall it's fine, if you're planning to watch the anime but wanna watch this movie too, then watch the movie first then the anime.
