No Game No Life is visual and suggestive exploitation and exposure of underage females pawned off as entertainment. And people wonder why the anime community receives so much hate and scorn and are labeled as "pedophiles" and stereotyped as fetishizing little girls.
There is nothing clever about this show. It's everything Death Note could have done wrong, done wrong. The main characters are already established as being unable to lose, so why become invested in anything they do? They're just gonna win anyway. It doesn't help that the rules of the game aren't even well explained half the time.
With 11 episodes, there's no room for any character development (not that they tried) and the characters themselves are barely established as people. They're just 2 no-lives who like gaming an unrealistic amount and are placed in a dream-fulfillment reality where you game to win. The concept is promising I guess, and there a few well-executed mind games, but that's as far as the creativity and entertainment stretches after you realize they actually won't lose, no matter what.
I don't really remember anything about the soundtrack (which shows how little impact it had), but I don't claim to be a soundtrack critic. A show should be good without relying on music to boost its score.
The art and animation is really the only thing the show does right. It was pretty fluid and consistent throughout and the backgrounds were well done. It was too bright and vibrant for my personal taste, but that's all it is, personal taste. It fit well with the fantasy setting, but my eyes didn't care.
This is a show perfectly tailored for people who want to see some indecent exposure and get a few good perverted giggles out of it and then pretend like it's a masterpiece because it's masquerading as a games anime. "Let's have an episode entirely dedicated to explaining the rules of the world and showing the consequences for losing. Then let's follow that up with a sauna scene where an 8 year old girl is almost naked as her brother gets hard for her and this other chick" HAHAHA FUCKING GENIUS WRITING!!! SUPER CONSISTENT THROUGHOUT!!!
Overall: 3/10 (For good art/animation and a few decent games)
