For me it was Serius. I totally loved him!!! And Harry deserved a parent like figure over dumbeldore.

For me it is also Serius because I started te get tired of Harry Potter after part 5. I was a total fan, but it took to long. And I know it is not the writers falt, it is mine. But I couldn't care less anymore.

I do have to admit that it was dumbeldore's death that made me cry.... not serius.
