I'm not going to lie. I cry every time I see this AMV/MMV. Akasaka really did care about Rika like a father would. Their relationship is probably one of the more emotional in the Higurashi series (Especially in the manga).
At first glance, this PV comes off as some horror PV but, if you read the lyrics and notice the symbolism, it's actually quite sad and beautiful in its grotesqueness.
Probably the only redeeming quality to this anime is this opening. It's stellar, but, with the exception of Seira, I found most of the characters irritating and the plot a case of lost potential.
