You must refrain from:

1. Elfen Lied - Pure Bullshit
   
   
2. Aki Sora - :fp:
   
   
3. Yosuga No Sora - :fp:
   

Warning -> Maid-Sama is one of the best rom-com out there. It has a great plot and barely any anime is upto its mark. Also the anime is incomplete. So you will have to read the Manga to uncover themysteries.

Most of them are main streams but still nice list though!

To me DBZ is just for people who don't like anime but wants to watch something.

Same with One Piece.

Elfen Lied was good :(

However the rest of the list is quite alright .
