Umineko No Naku Koro Ni

Clarification: I call ep 1-6 'filler' facetiously. They are integral and enjoyable but I personally liked how 7 & 8 brought everything to an unprecedentedly satisfying climax. I say this for anyone (including my past self) who dismissed the payoff and shelved it. If you've started don't give up, its more than worth it!
