The show is absolutely amazing. The studio did a fantastic job on the animation, especially the cg, I believe that it's the best cg art I've ever seen in anime. The only disappointment is that there isn't much interactions between the servants and ritsuka, which is also understandable due to the amount of servant and lack of time. I love how it shows fou's feelings at the end of the movie with words and incredible illustrations. Although i feel like it will be a bit difficult for those who didn’t play the game, but it's a excellent anime after all !
