Attack on Titan is an action, adventure, drama, fantasy and horror TV Series, it's also an animation made by the Wit Studio and the Production I.G. in Japan. There are 25 episodes of each 24 minutes and 3 seasons which one with 2 parts.

The story is about a hundred years ago, humans were nearly exterminated by titans. Titans are typically very tall, semm to have no intelligence and devour humans beings, and, worst of all, seem to do it for the pleasure rather than a source of food. But a small percentage of humanity survived by walling themselves in a city protected by extremly high walls of 50 meters. The main character is a teenage boy named Eren Jaëger who wants to know the secret about the titans and extermine them. He is determined, most of the time arrogant and reckless. The mood is dark, calm and stressing.

I'm giving it 9 out 10 because i liked the ambiance of the serie and it captived me to know more about the titans and the history of the main character.
