Story (7/10) Good
Adapting arguably the best and most favorite arc from the Gantz manga (as far as Gantz fans say) and starting from scratch so that newcomers to the series aren't 100% confused, I felt they did a good job keeping it a close to the original version. Sure the story in this version that took place before this movie was drastically changed and if you compare it to the manga sure it's inferior but like I said I understand why they changed so much, to mitigate as much confusion for newcomers watching a CG adaptation of an arc of a manga they've probably never heard of that takes place like 230+ chapters inside the actual manga. This is also the case for people who might have just been original anime only watchers to the early 2000s anime adaptation as this arc takes place so far ahead of were season 2 of the anime ended, other than Kato, his little brother, Gantz and Nishi everyone else they should know not of, hell the main character they were following for all of that anime isn't even alive in this one. So like I said above I felt they did a good job trying to making sure everyone is on the same page.
Art and Animation (10/10) Masterpiece
This is by far one of the best CG looking movies based off an anime I've ever seen. It's on par with Final Fantasy 7 Advent Children, Saint Seiya Legend of Sanctuary and Captain Herlock. And like I said when it came to those other CG anime to this, this is the only CG that I want to see anything else (like Beserk, Kingdom and/or even anything by Polygon Pictures) is borderline unacceptable and will leave at least one person unsatisfied.
Sound (7/10) Good
The sound was good, I even decided to watch it in english dub and it felt far less cringey than the early 2000s anime's dub as at times that one was painful and I regret watching it in dub but they grew on to me but man it took a hell of a while.
Characters (7/10) Good (Minor Spoilers)
All the characters were good and quite accurate their how they acted in the the manga. Although even though they are accurate doesn't mean they were very good. I still urk sometimes when I see certain characters act the way they do like Kato at times. Anzu Yamasaki in particular I didn't like in the manga and the reason I didn't like her in the manga was pushed even further in this version. In this version she's even more annoying and about the same level of rash and useless. And then Kato decides to revive her great worst girl lives. I mean I understand why Kato revived her that's something he would do in that situation (at least this version revived her and kept his promise the one in the manga said "fack dat I'm revive my boi Kurono lmao).
Enjoyment (7/10) Good
The most enjoyment I got out of this adaptation of the Nurarihyon Alien Mission/Osaka Arc was how amazing the CG was since I just finished reading the manga counterpart of this arc the same day and jumped straight into the movie a lot of the shock factor moments wasn't there (as they shouldn't be). Which I don't mind I was just looking for a good adaptation because like I said I felt even though with the changes they decided to make for this version at least they did a far better job than the live action 2011 movie.
Overall (7/10) Good
More Specifically (7.60/10) Good+
Before going into this I heard many many good things, did it live up to the hype? I mean I guess, I enjoyed it for what it was and not to sound like a broken record but like I said about two times before this adaptation did a good job and keeping all viewers whether you are an anime 2000s watcher only, completely newcomer to the series or a manga reader all on the same page to present this arc as a standalone more movie adaptations should follow suit.
