1. Mirrai Niki (future diary)? I've personally never seen this. So I have no opinion on it. I'll add this to my queue.
2. Naruto Shippuden? I used to watch Naruto religiously. Then for some odd reason I just stopped. There have been so many episodes since I last watched it that I've lost the motivation to pick up from where I last left off.
3. Deadman Wonderland? I really enjoyed this one. My only major complaint is that they set the show up for a second season, but I doubt that there ever will be one. From what I understand, this anime was only popular outside of Japan, so a second season probably won't happen. I've heard that the manga is very different from the anime, so I don't really know if I want to pick up right where the anime left off. Also, I didn't really like the unnecessary bleeps over certain curse words, but there's nothing you can do about that. :/
4. Attack on titan? I've watched this one as well. I really enjoyed it. I can't wait for the third episode of the OVA to premiere in August. By the way, if you haven't watched the first two episode of the OVA, I'd highly recommend it. They are very intriguing.
5. Another? I actually have this on my anime queue. I've been planning to start it for the past two days or so, but I haven't got around to it yet. I'll update once I've seen it.
