I've been meaning to write this Blood+ review for a while.
Blood+ takes vampire folklore and twists it into something unique and well suited to the series. Although, it may seem as if it would be a boring plot where a girl travels around hunting down vicious monsters this series is very far from being boring. From the first episode it stays true to the plot and remains consistent until the very end.
The atmosphere of Blood+ is rather intense. It takes a cheery high school girl and thrusts her into a dark world filled with violence, blood, and death. Being as it is a 50 episode series I had expected for the series to, occasionally, break from it's serious atmosphere or to become episodic. The series is consistent with both the story and atmosphere and never breaks. You witness the growth of both the storyline and characters to the point where the story is much more in depth than a high school girl with a katana killing off creatures. Watching anime I often expect for a random shot of chibi characters being silly and arguing about pointless things as to entertain or relieve the viewer from the seriousness of the series but Blood+ never makes an attempt at comic relief. Although, instead, they offer you a little bit of hope for the characters and their situation, as if things are looking up, only for it to be snatched away from you. It will literally drive you to tears. The plot will not disappoint you. It unfolds at a steady pace, and will offer you enough of a story and the characters that, at the end of it, you won't think, "I want more than this", you will just be completely satisfied with how everything panned out. Blood+ is rich with a beginning, middle, and end.
The characters of Blood+ are extremely well developed. As you watch the series it's as if you are watching them grow before your eyes. What I love about this series the most is how in depth and real the characters of Blood+ are. Despite having inhuman capabilities even the main character is of human nature in personality. In fact, you may even find yourself feeling sorry for the most sadistic villain of the series. Characters that are young and lack knowledge and understanding from the beginning mature as the series progresses. The situations they extract their experiences from make them grow stronger in character. Even if they know they are weak against the enemy they continue fighting as to support the one character who is able to end the misery brought on by chiropterans. Even adult characters that seem to have an understanding that the youth lacked are thrown into situations that cause them to experience something as a means of development in their character. A lot of the characters are often faced by the confusion of their own emotions and, as such, change drastically from their revelations.
Overall, the series was very enjoyable. It remained consistent to the plot and atmosphere with an excellent beginning, middle, and end. All the questions you could have had about the series are answered and you are not left in confusion at the end. The characters are strong, likeable, and well developed. After the very last episode of the series you could possibly be taken aback by how good the series actually was.
I would most definitely suggest you give Blood+ a try.
