I have asked this question before, and got good answers. However, I ended up finishing both of them. I would like it to be a shonen (shojo is okay, but not as great), with adventure and a little romance. Any length is fine as long as its not really short. I have read:
Naruto
Bleach
One Piece
Death Note
Fullmetal Alchemist
Fairy Tail
Rave Master
Black Cat
Psyren
Dragon Ball
Pokemon
Yugioh
Ouran High School Host Club
High School of the Dead
Ao No Exorcist
Vampire Knight
Soul Eater
Cage of Eden
Code Breaker
Zombie-Loan
Shugo Chara
Ga-Rei
Hetalia
Elfen Lied
RomeoxJuliet
Trigun
Rurouni Kenshin
Please don't suggest:
Yu Yu Hakusho (don't like the plot)
Inuyasha (everyone tells me the female lead is annoying)
Rurouni Kenshin
Katekyo Hitman Reborn
Naruto
Bleach
One Piece
Death Note
Fullmetal Alchemist
Fairy Tail
Rave Master
Black Cat
Psyren
Dragon Ball
Pokemon
Yugioh
Ouran High School Host Club
High School of the Dead
Ao No Exorcist
Vampire Knight
Soul Eater
Cage of Eden

Zombie-Loan
Shugo Chara
Ga-Rei

I also really enjoyed Pandora Hearts
