Story:
While the story isn't as rich as other shows in general, it is rather a very fresh take on human tragedy without reusing much of the usual apocalypse elements. There is also much lore in the world to keep creative fans making fanworks and adaptions of the world of Attack on Titan. The thrill element is very high and makes you eager to see what's next.
Keep in mind this anime covers only a portion of the manga and stops at the end of an arc. You will have to wait for the 2nd season or continue on in the manga.
Art:
The visuals are extremely unique in style and well done. The value here nearly matches an OVA/Movie feels.
Sound:
People are digging the opening song of the show as well as some soundtracks. However for me it is good but other than the opening, I didn't feel much uniqueness to the soundtracks or specific themes to get attached with. Voice acting is good enough but there is no memorable voice so far.
Characters:
There are lots of variety of characters and they have high appealing. However, in term of design and visual uniqueness, it is very limited since everyone is sticking to his uniform.
Enjoyment:
The action scenes are well done specially nearing the ending of the show.
Overall:
If you are into action, thrill, tragedy and want something that feels new, do not miss this anime.
