Fruits Basket, Nana and Monster
Elfen lied because it was my first anime. Skipped a whole day at school, pretended to be sick, to watch all episode at once :P Others can be Full Metal Alchemist (and brotherhood), Claymore, Death Note, Tetsuwan Birdy Decode, K, ...

Clannad (& the After Story) is by far the most beautiful story I've ever seen in an anime series - my absolute favorite. A few others (in alphabetical order, lol): Air Angel Beats! Bishoujo Senshi Sailor Moon Death Note Fruits Basket Hanbun no Tsuki ga Noboru Sora Higurashi no Naku Koro ni Hyouka Inu x Boku SS Kaichou wa Maid-sama Kamisama Hajimemashita Kanon (2006) Kimi ga Nozomu Eien Kimi ni Todoke Kobato. Lovely★Complex Ouran High School Host Club Skip Beat! Special A Steins;Gate Suzumiya Haruhi no Yuuutsu Toradora! ooops... Did I really say "a few"? Sorry, guys.

Ouran High School Host Club Vampire Knights Saiunkoku Monogatari Pretear La Corda d Oro Kaichou wa Maid sama Special A Fruits Basket Slam dunk Dragon Ball Gundam Wing
There are waaayy too many to list here, so this is a few: Full Metal Alchemist Brotherhood, Blood+, Shingeki no Kyojin, Bakuman 1,2, & 3, Shigurui and the ever popular Bleach and Naruto. As I said, there are many more, but we'll save some for later.
My fav anime is going to be Gantz it's a nice horror anime to see
The most underrated anime is: rainbow nisha rokubou no shichinin I can rewatch this 100 times and I wouln'd get bored. So many emotions, such a deep story, I loved it!!
My current favorite is One Piece!

Really fond of FLCL as well.
Hard to choose. If I only look at series I would say the following: - Natsume Yuujinchou (no matter how much seasons they make, they never get boring) - Kyou kara Maou (this makes me laugh every time) - Tenshi na Konamaiki (the main character is just too funny) - Special A (enjoyed the competitiveness she has) - Ghost Hunt (great story lines, still hoping for a sequel) - Vampire Knight (I know it is not the best anime, but sometimes you just love things you rationale know are not that great. Hahaha.) - Saiunkoku Monogatari (wonderful story, also still waiting for a 3th season) - Shiki (horror that makes you think about good and bad. Managed to surprise me in its story line)
Naruto, Hakuouki, Vampire knight
Not in any order: One Piece Mushishi Natsume Yuujinchou Ano Hana Puella Magi Madoka Magica Gintama Usagi Drop Ghost in the Shell (movies and all seasons) K-ON!
