I finished Sword Art Online II and thought the second arc was enjoyable and sad. I'm probably overrating it, but I give it a 9. It really does feel like I'm watching two separate seasons with the Phantom Bullet and Mother Rosario arc so it's hard to rate it. I also finished Ao Haru Ride and I really liked it, but it definitely needs a second season. According to someone on Yahoo Answers it will probably be unlikely due to the lack of content. For an anime that needs a sequel I give it a 9, but if it has a "read the manga" ending I give it an 8.
