Perhaps the author intended to make him evolve like Lelouch or Light Yagami, but not enough effort is put into making his character develop from the naive yet well meaning tragic hero, to a psychopathic nihilist warmonger (who is justified somehow for being so). The author fails miserably to make the audience feel sorry for him, or hate him either. He evolves from a protagonist with no charisma and personality to a villain with no charisma and personality. Maybe he was intended to become an anti hero on the same level as Lelouch, but he ended up being worse than Ouma Shou (guilty crown) in the same genre of anti heroes. The female lead Mikasa had zero character development as well, and she's basically just Sakura from Naruto except going Eren Kun Eren Kun instead of Sasuke Kun Sasuke Kun. Her not dying in the finale was disappointing because if Eren is her whole life, she might as well have been put out of her misery. Other than that, here are the individual ratings:
Art: 7/10 it actually got worse after S3
Characters: 2/10 Levi fails to carry an otherwise lukewarm cast of forgettable characters
Plot Twists: -3/10 No plot twists would have been better than the ones that drove this anime from a potential 8/10 to a 3/10
Music: 8/10 The only saving grace
Plot Progression: 7/10 It might be a terrible plot but hey it progresses!
Overall: 3/10 Watch it because you wasted your time on 88 episodes to get here, and then curse your fate.
