I've actually had Grave of the Fireflies for over two years now, and have yet to sit down and watch it. Idk, if I sit down and watch and anime that turns out to be tragic or sad without me having prior knowledge, I find it beautiful and tend to enjoy it for life. But, since I've known that GotF has these qualities wthout having watched it... I just cant get myself in that mood where "I think I'll sit down and watch this depressing anime that will probably make me sad".. I'm sure that makes sense. And I know I'm probably missing out.. meh, maybe one day soon.
