~Arakawa Under the Bridge - This anime is so eccentric and crazy, you just have to watch it xD
~Hetalia Axis Powers - So funny and fast paced, episodes are short so it doesn't take much time to watch it, and it's pretty cool to see how each country is portrayed.
~Kuroshitsuji - This one is way too awesome, The characters are so cool and everyone's stories are so interesting, and just go on and watch it because I could just ramble on forever about this one :3
~Natsume Yuujinchou - Go on and watch this RIGHT NOW because it is one of the most calming and likable series I have ever watched. You may be like "What the hell does she mean by calming?", but you'll understand once you watch like the first episode or two. It's on it's fourth season right now, but you'll fly by through the episodes once you start them :3
~Pandora Hearts - Really interesting, got me hooked from episode 1, they're are so many questions that you want answered after episode 1 that you have to keep watching. It's also nice to see how the characters develop throughout the series.
~Shiki - If you're looking for something a bit creepy yet intriguing, this one is a good one :3
~Soul Eater - This series has me cracking up (especially Episode 17) I love the characters and the story is really interesting.
Sorry for posting again, but I was typing for someone then someone else posted so I feel I should comment for the person that got missed >_< Skip me next person and do OhanaNiArashi
~D.Gray-man - Story is really interesting and makes you feel bad for the people who come in contact with the akuma. I love almost every character I have seen so far and the plot has been moving along well (I'm still watching it at the moment)
~Fruits Basket - Thanks to the main character, Tohru, it is anime that is so likable because of how sweet she is. It's also really funny and the plot idea is pretty interesting.
~Full Metal Panic? Fumoffu - This is so gosh darn funny, if you're looking for a laugh, this is perfecto :3
~Natsume Yuujinchou - As I said to Midnight-Sola, go watch this RIGHT NOW and look at the why I gave her :3
~Pandora Hearts - Also look at the Midnight-Sola post for the reason why :3
long enough PTW, haha
definitely Cross Game, it's got great characters and is good if you like slice-of-life. Also, I don't really watch sports anime, but I really liked the baseball parts
and Nodame Cantabile, that also is slice-of-life with really great characters, and it helped me further appreciate classical music
Detroit Metal City
Honey And Clover
Neon Genesis Evangelion
Revolutionary Girl Utena
Seto no Hanayome
Sword of The Stranger
Tales of the Abyss
Gurren Lagann Movies
The Cat Returns
Whisper of the Heart
So many good shows *-* It's hard to narrow it down, but I'd most recommend Ao no Exorcist, Another (though tentatively, as we still don't know how it'll end), Baccano!, Bokurano, Shiki and Tengen Toppa Gurren Lagann .
Another - Well you could wait for it until it's done though.
Bakemonogatari - I personally enjoyed it but different opinions are different.
Chrno Crusade - One of my first experiences but I enjoyed it, I really recommend it although the first bunch of episodes are like fillers.
