The story is well written for both anime and Light Novel; Volume 6, content delivery is very good and easy to understand. However, it is important to watch the TV anime before proceed to the movie since not everything explain from scratch.
Art : 10/10
If you like colorful anime you know NGNL have it but dark-themed of NGNL surprisingly went along with the story theme. It's the great war after all. Well drawn background and coloring, expected nothing less.
Character : 10/10
This part might containing a spoiler however reading this will not spoiling your experience.
Author, or rather Tet, made Riku and Shuvi similar to Sora and Shiro, keep in mind that they are not same person ( same VA though ) and Tet mentioned that he alter the story a bit so that the REAL story remain untold. In reality, probably that actually Riku and Shuvi look nothing like Sora and Shiro, but since it is 6000 years ago, the story look more interesting if the character similar to someone that we already know, Sora and Shiro. If they created entirely new character, we might not get the similar experience. ( Can you imagine an NGNL without loli heroine? )
Sound : 8/10
The sound is good, but not great. The OST goes well with anime with good impression but there's nothing catchy. If you fall in love with the anime, sound is not something that you'll hype, still it is good.
Enjoyment : 10/10
Watched this twice at cinema, further explanation is not required.
Overall : 10/10
This one will require math. Total of my score before is 48 which when divided by 5, resulting in 9.6 and after rounding off it, 10.
