TOP EDIT: And a tribute to a good image that was taken down from TV Tropes and now needs a home. Subaru, you're ten times more badass than Lara Croft.
So I've been marathoning this show today (at the complete expense of any work, I might add), and I'm honestly really enjoying it, particularly since I have absolutely no idea what's going on. It's a novel experience, honestly. I can't even describe the damn premise, I don't get it myself. Ah, what the frak, here goes.
So back in 1986, a rich family showed up on their own personal island with some servants to conduct a business meeting with regards to the passing of their patriarch. There's a legend surrounding the family and the island with regards to an ancient witch who formed some sort of contract with the patriarch to get the family finances up, and now she's come to collect on the debt owed.
People start getting brutally murdered, and the whole thing's a mystery as to who did it. The real question is, is there actually something supernatural going on or not? I don't have a damn clue, and I'm just waiting to see how it ends. Go watch it yourself.
Edit: I caught up with the fansubs. Still hooked, still absolutely clueless as to how things are going to go down.
