Attack on Titan (Shingeki no Kyojin): As of now, I'm 4 episodes in, and I'm calling this my leader for Best of 2013. This show has everything short of romance, and the acting backs it up.
HOOOOOLY SHIIIT, I just watched all the episodes(5 so far), and I have to say that it blew my mind, as the spectator I could never catch a break, every time I thought it was over something always popped up, I highly recommend this series. Also is very graphic(something that I don't like but this is the exception), I think that they want you to understand or better said, they want you to feel sympathy, feel the fear of the characters, and I guess they did an splendid job because I do XD.
Also if you never watched Hunter x Hunter, you barely remember it, or you want to just revive the past I recommend to watch Hunter x Hunter 2011. At first is hard to to watch it because is too cartoonish and it looks like a 5 years old show, but as the show progresses the drawing gets better and so the fights and animation. I would say that it really gets interesting during the hunter exam, and goes up from there.
