so many i like
 

um...inuyasha's pretty good. naruto, chobits, .hack/// is ok. ah! my goddess was very good. OMG. WACTH ELFEN LIED. NOT EVEN JOKING AROUND. WACTH ELFEN LIED. I CANNOT EXPRESS IT. SO SAD AND SAD AND SAD AND BLOODY. WATCH IT.

oh, and Air was very good. another sad one...but very good

I would recommend Beck, The Third:The Girl with Blue Eyes, Pumpkin Scissors, Death Note, Blood +, Welcome to NHK, Naruto, Bleach, Gundam Seed, Blue Gender(even though its old), Tenchi Muyo GXP, and Noein.

I just finshed watching WitchBlade which was pretty good. It seems more directed towards guys since the women have big chests and arn't wearing much, but i'm a girl and ignoring the half naked women it's pretty good when it comes to the storyline and the action.

I don't know what kind of manga you like so I will split into categories:

Ecchi/Comedy:
1. Mai Otome (kinda in between Ecchi/Comedy/Action)
2. Mai Hime
3. Ichigo 100%
4. Ranma ½
5. Girls Saurus DX (be warned almost makes no sense)

Action:
1. Inuyasha
2. Bleach
3. Naruto
4. DNAngel ( A must read! also is Romance)
5. MAR

I could list more but I'm lazy.

Anime
1. Suzuka
2. Tekkonkinkreet
3. Melancholy of Haruhi Suzumiya
4. Air Gear
5. Welcome to the NHK

Manga
1. XS Hybrid
2. GTO The Early Years
3. School Rumble
4. Train Man
5. Welcome to the NHK

These are the current anime/manga I am into right now.
Maybe you will like them to.
I conciser them all to be pretty new.

I would reconmend Naruto

for different genres


Wacky Semi-romance:
Welcome to the NHK

Action romance anime:
Kaze no Stigma

Straight Romance:
Hantsuki, Air (The Movie version)

In the mood to just laugh randomly? Watch Seto no Hanayome.

I wouldn't be doing my job as an anime fan if I didn't recommend

Death Note
Vampire Knight
Godchild
Loveless
Ouran High School Host Club

ANIME:
Gunslinger Girl
