Vampire Knight is one of those endlessly long stories that are gettting more and more boring and clichéd by the time.
I loved Hino Matsuri's Merupuri. It was a cute, fantastic story full of cliffhangers that always kept me in suspense. When I started reading Vampire Knight, I expected an intriguing, authentic, dark and even more suspenseful manga, but what I have got is somewhat disappointing.
The two main vampires, Zero and Kaname were pretty interesting in the beginning, but after a while, Zero's neverending self-pity and cold attitude and Kaname's predictable reactions and typical vampire behavior started getting me on my nerves. As for Yuki, she is an ordinary, powerless girl you can find in the most shoujo mangas. She has been simply annoying and dull from the start.
Although the concept of the story sounds promising, it is at least as tedious as the characters. The twist are boring, plus there are a host of mulling and pondering in the story that always make me want to jump to the next chapter. I guess Hino Matsuri herself is extremely bored with her "masterpiece".
All in all, the whole manga is a great disappointment. The drawing style is amazing as expected from the mangaka, but the story and the characters have got no potential. I give it a three because of the eye candy and the good start, and try to avoid everything VK-related in the future.
