cause they didnt come back....so no happy ending

Clannad by far.

agreed with berto i mean Clannad wasn't really that sad because of the happy ending beautiful i grant you though.

Angel Beats.. They died. Poor Iwasawa, I feel the worst for her.

Clannad and Angel Beats were both really sad to me.

i cried my eyes out

Clannad did have a happy ending, but it was sad and Angel beats was too..

Where was AnoHana?

clannad! It could make everyone cry!

For me it would be Clannad, then Air & Angel Beats would be tied, i have yet to see AnoHana, though iv been really keen to watch it.

i just already watch clannad...DX

but i'm already read the synopsis of anohana and angel beats, they say they are sad animes...DX

Angel beats is sad too

All *sniff,sniff*

It made me cry and I never cry when watching something

I didn't find the other four to be sad.
