Shingeki no kyojin otherwise known as Attack on Titan. This series before the anime wasn't popular in the west, but it was fairly popular in Japan being in the top 15/10 best selling manga in 2011/2012. After the airing of the anime it became a mega hit series.
Now before you give this review a not helpful vote because of the 10/10 score. At least read what I have to say before doing your deed. I'm more interested that you guys read my review than anything else. Now let's begin!
"Spoiler free review!"
Story: 10/10. The plot/story IMO is snk strongest point. "Titans" these monstrous looking creatures that
comes in different shapes and size. Their main and only goal is to eat "humans" 100 years ago humans where forced to live Inside the walls which are over 50 meters tall, to stop the titans from getting in. This series is full of mysteries for eg. who or what created the walls? Are titans natural creatures? Who created titan shifters? Why were they created? This is just a small dose of the amount of mysteries in snk. Snk is a mystery series with horror elements in it. The plot/story is snk strongest point, but it can be a disadvantage to the series itself. Why? Because the story is setup in a way where it doesn't spoon feed you answers right away, and if the readers don't pay attention to the story. They will forget things that were earlier "foreshadowed" also the series being a monthly manga doesn't help. A lot of complaint I've heard about the series is that it feels like the author is making up things as it goes or pulling things out of his ass. Now this isn't the case. Snk is one of those series that gets better when you reread it. When you reread the series you will see the amount of foreshadowing/hints the author puts in the early chapters of the series. Things that has been foreshadowed in the very first volume is now being answered currently in the latest chapters of the manga. What does this tells you? It tells you that the author has planned out everything already, and he already knows how the story will conclude. The world building in snk is impressive! The amount of details the author puts in his world building is just great. Thd mysteries of the series and the overall plot is just so engaging. You just want to know the answers. This is one of the reasons snk has a lot of theory threads around the net. You know the TV series called "lost" that's the vibes I get from snk story. Except snk will answer our question and not give us any bullshit....I'm not going to go there. Anyways read over this series at least once. You will have a better understanding of the overall plot. And you will be less likely to ask stupid questions. Sadly not everyone is willing or have the time to read over the series. Sigh.
Art: 8/10. You guys must be saying in your mind. "what!? O.O 8/10 for snk art? fanboy alert!" lol, let me explain why I gave it a 8/10. At first I didn't like the art. But I slowly started to like the art. The main reason is because the roughness in the art fits the horror theme very well In this series, I don't think the series would successfully have the "horror" feel to it if it had something like, the Levi spin off manga. I do have to say I don't think the art is as bad as people are making it out to be. I think the scan is mostly at fault for this, if you buy the actual volume you will notice it looks much better than the online scans. Compare crunchy roll scans with manga panda and mangastream scans you will see a difference in quality.
Characters: 8/10. A lot of people say snk characters are flat/one dimensional. You will also notice that most of the peeps that said it are anime only viewers. Now, the first 30+ chapters which is basically the 1st season of the anime are mostly use to introduce us to the big cast of characters. The author flesh out the 3 main characters which are Eren, Mikasa and Armin. The secondary characters are not shown too often so obviously the readers won't be too interested in them. And I'm not talking about redshirts characters I'm talking about the characters that we will get to grow with during the series. IMO. Armin and jean got the most development in the first 30 chapters, although they are both my least favorite characters. Now around chapter 35 is when the author starts to give focus on the secondary characters. And start to flesh them out more as in making us know their motives and also how they fit in the story/plot overall. There is a few more characters that needs some fleshing out/character development. But overall Isayama is doing a solid job with his character especially in a story driven series. About the female characters, I like how he balance it out as in making both the male and female cast both having important roles in the story.
Enjoyment: 10/10. This series is very enjoyable. Not only it has a great story but also it has plenty of action in it that gives me goosebumps. I also like how strategic the fights are in attack on titan especially when it comes to titan vs titan fight. There is no get angry enough and you will win type of fights. Female titan vs eren is a good eg. And I'm not talking about the anime filler with fire titan eren. Or power of friendship defeat the bad guys. If you don't stay calm and think logically you are going to lose. Finding weaknesses and exploiting them is what attack on titan fights are about. Eren vs armored titan is another good eg to that. overall I enjoy the living hell out of this series. The conspiracy, the mystery, the action/horror it all makes this series a series to remember.
Overall: 10/10. As I said before, if you want full enjoyment for this series. Re read it. If you are caught up and you're lost on the plot or you just feel you're forgetting things. Just reread it, pay attention and analyze everything. When you reread this series you will notice a lot of things you didn't notice the first time. Its also funny when you're rereading the manga and you know all the traitors in the series. You will also see how suspicious they were. Anyways time to wrap things up. Don't breeze through the chapters when reading it, take your time and enjoy the series for what it's. Whoever that has made it this far, thnx for reading! And I hope you have a wonderful day.
