The biggest flaw with this show is how it ruins a good game by not treating the characters right. The characters are reduced to simple character traits instead of the more complex depths. Daichi is a comical coward who has weak demons, instead of the unsure, but determined friend who acts as the audience surrogate. Yamato is turned into a villain instead of a complex Anti Hero/Anti Villain depending on how you view while also making his obsession with the protagonist, Hibiki, be played up to homosexual subtext combined with Yandere control. By far the biggest offender is Joe, Otomoe, Ronaldo, and Fumi, who all are used for three episodes each and die with no build up. Fumi also dies in the worst way, doing one thing to help fight before being one hit KO'ed.
The lack of comedy also is a big slap since the game is filled with comedic moments to break the tension and suspense. When a character cracks a joke in game, it's to reassure and lighten the mood but also to raise morale. In the anime, it's fanservice jokes and nothing much.
The story has no foreshadowing to it's obvious ending. Obvious being that they had to do the expected ending because they messed everything else up. The problem is that it isn't set up right and the anime treats it as the right and natural path. As if saying "This was the intended route guys!". It also doesn't explain our Angels-I mean Septentrions, since it makes Yamato the Final Boss instead of the main, real threat thats established in game half-way through. It's a big F-YOU to the fans of the game, especially since it doesn't add up once put under the analysis lenses. Basically it abridges the game but instead of using a shortcut, it blows the whole bridge and shrugs it's shoulders.
Then there's the inconsistent story points. For example, main character Hibiki has super strong, level 40 in game demons at the start with no context why yet other characters get around the same level of demons in relation to the section of the game. There's no justification in story and the fact that the strategic team fighting is reduced to "Hibiki can save us were team fodder" is stupid.
All in all the only good things are great animation, soundtrack, and voice cast on the subbed verison. If you watch the dub, don't. It's a horrible dub. Everything else is just horrible, offensive, and sad to see because Devil Survive 2 is a great game. It's avaliable on the 3DS with a great voice cast and storycontent.
