A good site to watch on is
WatchCartoonOnline.comI like Death Note, but the manga is better than the anime (More Matt. But his role is short, and even shorter in the anime.)
I also like Fruits Basket as well. And Mushishi. Mushishi is darker and a bit confusing, but that's only in the beginning. It's about a guy who goes around helping people with problems relating to mushi (Go watch the first episode)
Hetalia is really funny. It's a comedy about personified nations. The first two seasons mainly take place in WWII. It's very stereo-typical, so don't get offended at your country. I prefer the subbed version. Seasons 1 and 2 aren't bad for the dub, but 3 and 4 are much better subbed. It makes more sense (Also the movie is much funnier subbed. Dub sucks)
Ouran High School Host Club is funny and light. It's about a girl who looks like a guy and stumbles into a host club at a high school and breaks something, and so she starts working with them to pay off her fee.
Soul Eater is pretty interesting. Watch it, cuz it's kinda hard to describe xD (Go Death the Kid!)
I have more if you'd like, I just can't think of them at the moment... I watch too much.
