wat a good anime (i need a new 1)

This is tough to answer since I don't know what kind of Anime you like. So I'll list some of my favorites. I like COMPLETED Anime's best :)
If you want more serious: Death Note is great. Trinity Blood, Vampire Knight, and Vampire Knight Guilty.
Funny: Trigun, and Axis Powers Hetalia.
Romantic Comedy: Ouran High School Host Club. Pretear is one I just watched, it's only 13 episodes long but it was pretty funny, romantic, and had action. It was kind of Sailor Moonish with the costumes though lol.
Another Romantic Anime that I'm watching now is Lovely Complex. I've laughed quite a few times and it's very cute so far. Hope I helped!
