What are some good animes to watch?

Then I would highly recommend you to watch Prince of Tennis a.k.a. Tenipuri...It's really awesome and easy to get attached to it...It has some comedy and of course has tennis in it...!~

K-On would be my first suggestion to you... it as a lot of funny moments, good music and I found it easy to get attached to... after the first couple of episodes, from season 1, Found myself hooked. Other suggestions would be Ouran High School Host Club, Usagi Drop, One Piece, Fairy Tail and Mahoraba: Heartful Days.

Soul eater. its funny, and quite short. You get attached to it like that! * snaps finger *

Hummm Hetalia, Black Butler, and Death Note....

You would probably like:
[pictured] Durarara!! (Action, suspense, funny, interesting)
Zombie Loan (horror comedy)
Psychic Detective Yakumo (suspense, ghost, powers)
07 Ghost (interesting story, funny scenes, cool world)
Blue Exorcist (action, humor, epic fights and characters)
Daily Lives of High School Boys (Hilarious!)

Also if you want one that you will get attached to, try Natsume Yuujinchou. It has a little bit of everything and the story and characters will draw you in. Great story, wonderful message, interesting plot, lovable characters, beautiful drawn. It has easily become my favorite anime. But it isn't a darkish anime like Black Butler or Death Note so not sure if it will be your type.

Gintama is a very funny anime.
there is the Edo era when is about 200 years ago, but a lot of aliens come to Japan. And culture is higher than now. The main character is called Gintoki.
