AFAIK these are the only 5 I've seen. These aren't all my favorite but I'm listing them all anyway, in order of preference.
Elfen Lied was amazing, and I loved it. A lot of sad/touching moments.
Death Note was great, and kind of made me think differently, though at times it dragged on. Had great plot twists though.
Naruto Shippuuden was pretty good too, although I prefer animes with around 20-30 episodes. I get too lazy to continue.
Lex showed me Bokurano which was kinda cool, but I stopped watching after I only had like 5 episodes left. I don't know why. The theme song 'Uninstall' is
loving amazing.
Paranoia Agent was really cool, but then I started not liking it I think, and I stopped watching.
