I passionately love Attack On Titan and the anime. However, I watched the anime first because it's best to watch than read it first so you can really connect with the characters and the feels. At first, I intended to wait for the anime to finish then read the manga itself. I was pretty good at resisting it for a long time. But then, I really couldn't get enough of it so I just had to read the manga - only the first couple of volumes. Then, I can wait for the second season. 
 So, what I like about the manga: 
 How detailed it is. I read a lot of manga and this, so far, was one of the most detailed works I've seen. The buildings and action are realistic in a way that brings out the characters and and how they work around them. It's so mesmerizing to me. 
 The differences and similarities from the anime. I'd be pissed off I ever learned that the anime is nothing like the manga. Though, this time, the anime followed the manga story which is surprising for me. But, I also like that there are small differences. That's partially the reason I want to read the manga. 
 The rest of the review will come. Sorry about that.
