Loved this anime. Very interesting story that was definitely something you haven't seen before. I loved the animation, very clean. Sound was great, and the only complaint I have on the characters is that they are stereotypical - the quiet, shy Sakura, the too-cool-for-you but popular Rin, even the reserved and closed off Saber [not to mention Illiya or whatever her name was]. Nevertheless, it's well-known stereotypes that we all still love to watch, so I didn't have much of a problem with it. The main character, Shiro, did slightly annoy me at times with his "saving everyone" bit, but it was still an awesome anime that I'm happy to have added to my repertoire. Definitely worth the watch. Go to episode 2 or 3, when the plot really gets going. If you still don't like it, you can always drop it and only have lost an hour, but definitely give it a try.
