Ef A Tale of Melodies
Sayonara Zetsubou Sensei
Record of Lodoss War OVAs
Phantom Requiem For The Phantom
Adolescense of Utena
Highschool of the Dead
Saint Seiya (childhood fave)
Magic Knight Rayearth (another childhood fave)
And, with a handfull of exeptions, everything from Studio SHAFT
Tiger & Bunny
And a few others that are just mindless entertainment and not really worth mentioning.
Would recommend but not a favorite
Don't get me wrong, I love the series very much, but I've never been able to completely look past omissions in the anime having to do with the ending, wich makes a heck of a lot more sense after looking into a certain game mechanic in the VN. Regardless, I wholeheartedly recommend it by always saying: "Clannad is life".
