Attack on Titan is a fascinating animation. It's a well-produced, rendered, and paced piece of work. It captures the horrors and devastation of being assaulted by otherwordly, fresh-eating giants known as titans. Oftentimes circumstances are stark with military maneuvers being formed out of desperation, and with every sacrifice, the dwindling parties tread painstakingly closer to the truth. Every episode contemplates mortality and, consequently, the meaning of life. When all is done and over, what will have mattered are the relationships with comrades and family served and lost, leaving a flickering hope of the survival of humankind in a sunken cost mentality. Maybe when it's all over, humans will finally be able to reclaim their freedom, and no extent of loss can deter that hope.
Wit Studio judiciously releases seasons over the course of years, giving the writers sufficient time to further the plot in the manga. The art style and the pacing of the action scenes either rivets or arrests the anxious heart. The tension between life and death--and how the trajectory of plots anchor on the thread of survival of the show's primary characters--is evocative of Game of Thrones. If there's any animation I recommend today, it's this anime.
