Fun fact: The Girl Who Leapt Through Time also won all of the aforementioned categories in 2007. But there's one award that Summer Wars nabbed that Girl did not: Best Feature Film. (Girl was beaten out by Paprika and Arashi ni Yoru ni in this category.) Having thus surpassed its predecessor, all I can say is: congrats, Hosoda-sensei, now bring the freakin' movie to San Francisco already.
Production I.G's Eden of the East and Kyoto Animation's K-On!, the Best OVA was Eve no Jikan/Time of Eve, and the Best Foreign Animation went to Wall-E. (Yay!) Hiroshi Kamiya won Best Voice Actor for his work in Bakemonogatari as our hero, Araragi-kun-- you can hear him now as info broker Izaya in Durarara!! over on Crunchyroll. And finally, Evangelion 2.0 You Can (Not) Advance took home the Best Music award.
Also of note: Fumiko no Kokuhaku, the hilarious YouTube short which you may remember, was among the Award of Excellence for a Student winners. Awesome!
What do you think? Did you see any series in the last year that you thought should be here, too?
