Attack on Titan (Shingeki no Kyojin) is easily one of the best, if not THE best TV show of all time. Everything from the characters, to the setting, the the titans themselves are perfectly done. The atmosphere the show provides is also very noteworthy with it's music, camera angles, and animation. The show takes place in the year 850, where creatures called titans showed up on earth. They basically eat people and are extremely hard to kill. The remaining humans built several walls to keep the titans out. Needless to say, the show starts when something goes wrong and humanity must be saved. The show may seem to have a pretty basic idea, but it is so well done and has plenty of twists to keep the viewer on the edge of their seat
