This was one of the first animes I ever watched. I watched it with a couple of friends at the time and I fell in love. I've seen Ouran a total of five times, both subbed and dubbed, and I've also read the manga. Still waiting for a second season (maybe in 2016?).
This anime managed to finish a beautifully developed plot, build up and break down characters, touch on the morality of humans and sacrifice, and amaze with brilliant animation all in 64 episodes. Saying that FMA: Brotherhood is one of the best, if not the best anime, is not an understatement.
