Blue Exorcist is a great anime for any shounen fan out there, or anyone that just wants a taste of anime for the first time.
Published by A-1 Pictures (Black Butler, Sword Art Online, and various other titles), Blue Exorcist provides enjoyment with its variety of characters and nice animation. It focuses on the ironic idea of a demon killing demons; and, not just any demon, but Satan. The first episode goes directly into the story, and, at least for me, hooked my attention. The introduction to this series was well-thought out, even if it was in a few episodes. The thrilling soundtrack produced by Hiroyuki Sawano (Attack on Titan, Kill la Kill) keeps one on their feet through all the battle scenes.
Because the manga is ongoing, this 25-episode anime had an original ending (much like the original Fullmetal Alchemist series). This, I feel, was one of the weaknesses of Blue Exorcist; it felt a bit rushed, and did not completely focus on the story. There are very many unnecessary filler episodes, and, while they do give the other characters the "attention" (thus the effective character build-up), it seems as though the conclusion of the series isn't focused on until the last few episodes.
As I mentioned before, this anime has a large variety of characters with different personalities. And, as I also mentioned, the filler episodes help chracterize them. Each character is their own person, each with a reasonable amount of screen time. One can easily relate themselves to another character in Blue Exorcist because of this.
Blue Exorcist has left an impact on me through its beautiful way of conveying the thoughts and feelings of all the characters. It teaches one about sacrifice for those close to them, and the challenges one must overcome to achieve their dream.
If you are searching for an anime with a well-thought out story, Blue Exorcist is highly recommended. The action scenes will leave shivers down your spine, making you want to watch the next episode immediately. One may simply fall in love with the abstract characters and melodic soundtrack. Blue Exorcist will most certainly satisfy your anime dosage, whether you may be a rookie or an amatuer.
