Not to be biased, as I found this to be a pretty good manga, but I'm not going to go fangirl here. Overall, this was not bad. I can't say it's generic, as it's the hit of most vampiric graphic novels. It stands, (or stood,) as a representation of vampire romance.
Art: It's sweet, with gothic representations. The girls are pretty, the guys are loved. If you're looking for a hit with good art, this is for you. (Don't forget /vampires/ with good art.) Warning: looking at gothic styled eyes will get you slightly frustrated. And also, there are about three expressions. Happy, angsty, and neutral.
Plot line: It changed, but it was interesting. There is incest, and it became a real turn-off. The past... 10 chapters I believe, went slow, with no real goal in mind for how the end could be rounded off. I believe this should have ended around the same place the anime ended, except formulated not so abruptly. I wish it didn't drag.
Characters: Sorry, but they're done. Zero seems the same since the beginning, and Yuki has the same face and "pain" for the same scenes. Kaname bears the same unduly face as well. Flat for the most part, with bursts of angst at some points.
It was funny, in the beginning, and it was slightly tear jerking. (But I'm a wuss, I know.) I'm not bashing the looks of the main characters, only the context. (So don't fangirl me D: ) The plot line should have died a while back, but if you want to read some romantic edgy vampires, go ahead... for now. 😀
