Fullmetal Alchemist: Brotherhood is a masterpiece of an anime. It is near perfect and I doubt if there will ever be any anime that can surpass or match it. It has everything that is needed to make a great anime; story, characters, art, music and all of them are top notch.
Fate/Zero is a prequel to Fate/Stay Night but it is the best anime of the series. It’s an action packed joyride that will keep you at the edge of your seat with its amazing story, a great set of characters, nail biting sequences and breathtaking animation.
Ao Haru Ride is a breath of fresh air among all the romance and shoujo anime. It has a very simple story and a small set of good characters. It has great moments of laughter. Overall it is a great light-hearted anime.
Steins;Gate is by far one of the best anime out there in terms of story and characters. It’s a Sci-fi/mystery/thriller anime that will take you through an emotional roller coaster ride.
One outs is really good but highly underrated psychological and sports anime. Combined with the mind games and a badass protagonist, this anime is in a league of its own.
