- Tengen Toppa Gurren Lagann (27 eps; awesome, hot-blooded manly shounen action; mecha and boobs abound)
Mushishi (26 eps; standalone eps, supernatural mysteries; very Japanesey without being esoteric; excellent OST)
Fullmetal Alchemist: Brotherhood (64 eps; better than the first FMA anime in every way)
Panty & Stocking with Garterbelt (13 eps; amazing animation; fanservice and potty humor and weird artsy *)
Planetes (26 eps; realistic sci-fi, slice of life shenanigans; has a very good dub)
Chihayafuru (26 eps; unexpectedly adorable josei series)
Nodame Cantabile (23 eps; hilarious and very sweet josei series (but the sequels suck))
Darker than BLACK (26 eps; supernatural action/mystery/awesome (the sequel is terrible))
Ouran High School Host Club (26 eps; very meta satire that is still a tried and true shoujo comedy; surprisingly excellent)
Baccano! (26 eps; immortal alchemists in 1930's New York; that is all)
I * love Code Geass, but I think watching it now and watching it when it aired with speculation abound are two very different experiences. It's very flawed. But it's still very fabulous.
Anyway, if anyone checks these out, lemme know what you think. I think I wrote long reviews of most of these, too, if you want tl;dr (but still spoiler-free) opinions.
