It wasn't that bad. Certainly not the worst video game to anime animation. I think they're doing good with it but sometimes I feel like they're doing it wrong in terms of how they progress through the story. Glossing over bits and going too much into needless stuff etc.
They certainly do make you feel for the characters though. Especially during the most recent episode, where we got to see a bit of Nitta focus, but then again she still seems as the generic female frail girl of the anime. Yamato will always and forever be a giant meanie-poo. I don't know why everyone just doesn't rebel against him.
