Tell me a good anime to watch :P

Higurashi no naku koro ni.
Best anime I know. :)

Ninja Scroll

HELLSING OVA! The most epic anime ever.

Eureka Seven, The iDOLM@STER, Rocket Girls, Element Hunters

^ E7 is more epic.

Boku No Pico, its one of the craziest animes and best. And Seitokai Yakuindomo.

Elfen Lied.

Inu yasha

There are some extremely valid suggestions in here, but there are also a huge amount of just plain average titles as well.

Some of you are even suggesting Bleach...... are you guys serious?
Come back again once you've watched a respectable amount of anime =.=

(FYI, I'm on 9896 episodes watched with 153 days 4 hours of my life wasted due to anime...)

Blue Gender.

Tsubasa Reservoir Chronicle

Clicky

Apart from the usuals, Baccano! y Dark than Black. I love them.

Eureka Seven or Gurren Laggan!

Tiger & Bunny, Mirai Nikki, Code Geass, Death note, Gurren Lagann, Melancholy of Haruhi Suzumiya, FMA:Brotherhood and Clannad.
All I can think of atm.
EDIT: Oh and Detroit Metal City, that shit is crazy.

Slayers

Appleseed.

CODE GEASS

Akira, Vampire Hunter D: Bloodlust, Vexille: 2077 Nihon Sakoku,Neon Genesis Evangelion and Elfen Lied of course

flcl. just, whatever you watch, don't watch it in english. unless it's cowboy bebop, best dub ever.

A good anime that doesn't seem to be mentioned at all is bakuman, only watched first season (then went on to read the manga).

Code geass, Steins gate, One piece, Eureka 7, Ergo Proxy, FMA.

Fairy tail

Both seasons of Code Geass, all 3 seasons of Black Lagoon, Ghost in the Shell, Tengen Toppa Guren Lagann as well as Macross Frontier are some of my all-time favorites.

Fate/Stay Night
