I heard that it was the best anime ever from some people and others said it was highly over-rated so they didn't like it. Personally, I think it wasn't the best anime ever but it's definitely one of my favourites.
I really liked the art for some characters, but I wasn't a fan of the way some characters were drawn. The titans looked amazing and their facial expressions were done really well. I liked how Levi, Mikasa, Petra, Eren, Christa and Sasha were drawn and there are more, but I'm going to stick with those six.
The titans were my favourite thing regarding the art, they just looked badass, especially the Colossal Titan. They just looked really cool.
I really liked the characters in Shingeki no Kyojin, there was one maybe two that annoyed me but I really liked the rest. I really liked Levi, Mikasa and Sasha. I think each character has their own unique trait and that it makes them better.
The story was amazing, I really liked the intro to what happened when the titans first appeared. The story was really interesting and I became kind of obsessed with Shingeki no Kyojin.. The story was captivating and really enjoyable. And I love the 3D Maneuver Gear, it looks like so much fun.
Overall I love Shingeki no Kyojin, I don't think it's the best anime ever but it's not far off it in my opinion. I recommend you give Shingeki no Kyojin a try and decide for yourself if it's over-rated or if it is the best anime ever or if it's just really amazing
