[Shade]

Suggestions please?

Animes that I have watched  fully:

D Gray Man
Zombie Loan
Death Note
Dragon Ball Z
Full Metal Alchemist
Trigun
Claymore
Naruto(this does not count shippuuden)
Soul Eater
Digimon seasons 1-4(season 3 and 4 are awsome(season 3 is better then 4))


Still going on series:
Bleach
One Piece
Dragon Ball Kai
Full Metal Alchemist Brotherhood
Naruto Shippuuden

Fullmetal Alchemist: Brotherhood

If you've seen all of the first Fullmetal, the first 10-15 episodes won't be too interesting. If you haven't seen the first Fullmetal, you'll probably really like this anime, but even if you did, every episode past 15 has been great! Looking forward to the next episode. Oh and you can download the episodes in 720p, that's a big plus for me.

I have watched it to its latest episode.

Dead Leaves.

Anime short; its about one hour long but it kicks soooo much ass.

Trailer!  http://www.youtube.com/watch?v=vmsOUiQA ... re=related

Also Foolie Coolie/Furi Kuri/ FLCL/whatever is an obligatory suggestion.

Their use of color is strikingly similar, but that's about as far as it goes.

Why don't you try Code Geass?You would have to probably have to watch it on youtube though,because it's like on and off on adult swim.....

[CupOfOrangeJuice]

Suggestions please?

Watch Studio Gibli and Miyazaki films.  They're usually pretty good.

[SentinalBlade]

Bandit King Jin (like 14 epsidoes, but the alcohol references made me lol and its short sweet and entertaining. its not as serious)
Gun Grave
Fate Stay Night
Ju-yu-sai-oh
Tactics
Gilgamesh
Wild Arms: Twilight Venom(id give it about a 6.8...its still entertaining, due to the Arms reference form teh wild arms PSX series)
Darker than Black
Boogie Pop Phantom(really cool, despite the name)
Cowboy Bebop(im surprised you saw trigun and not cowboy bebop)
Chrono Crusade
Tsubasa Resevior Chronicles

[SilvasRuin]

Monster

Johan makes Light look like a complete joke, and he doesn't need a magic book to do anything.  It won't be immediately obvious why people think he's worthy of being called a monster, but stick with it.  He definitely is a monster.

[FFMaster]

Fate Stay Night
Higurashi no Naku Koro ni
Umineko no Naku Koro ni
Code Geass

[DarthPaul]

Tsubasa Resevior Chronicles

^Watch the first two episodes of this then watch the OVAs/read the manga.

Higurashi no naku koro ni
Umineko no naku koro ni
The melancholy of Haruhi Suzumiya
Clannad
Rozen Maiden
Azumanga Daioh(only watch this if you've been out of high school for about a year and a half or more or you will hate it.)

[Kaijyuu]

Now and Then, Here and There. (Ima, Soko ni Iru Boku)

Don't read any plot synopsis or anything, just watch it. It's 13 episodes long.

[Archael]

none

go watch district 9 instead

[Piercewise]

Cowboy Bebop (especially if you watch dubs)
Samurai Champloo (same team as above)
Baccano

[Asmo X]

Anime will lower your intelligence. This is scientific.

[Shade]

Actually it seems that it raises.
Mozart watched Anime.
