Shingeki no Kyojin is what many people say is the best anime of all time. Well I will disagree. Shingeki no Kyojin also commonly known as Attack on Titans starts out as a potentially strong anime which quickly left an impression. After continuing to watch the series what I released was:
Story: The Story itself was good but it lacked tons of originality. It really had me thinking why is everything too predictable. Then after some researching I found out Shingeki no Kyojin was inspired by Muv Luv. The story itself changed into a more shounen version of Muv Luv but it did have a little originality and overall the story wasn't bad just not original overall 7/10 for story.
Art: I didn't really like the art starting out but I can't see any other art style fitting the series better so I would give it an 8/10 as far as art is concerned.
Sound: Overall the OST and VA's were pretty good not much to really get into 8/10.
Characters: The character development in Shingeki no Kyojin is Eren episode 1-5 character development. Every episode after that focused on side characters having great character development though. But the main cast besides Armin seemed to digress overall. 6/10 for characters.
Overall I really enjoyed the series and would like to see a second season. My overall rating for this anime would be 8/10. I would recommend to anyone into action and supernatural anime. It was a good ride while it lasted.
