I have a strict rule regarding openings and endings: On the first and last episode of every series, they MUST be watched, no matter how much I dislike them. Why do I do this you ask? I have absolutely no idea Of course if I enjoy either, I can watch them whenever I want, but I rarely watch them every time. Although while watching Higurashi, I enjoyed the opening every single episode, but to be frank, I thought Higurashi was crap and the opening was the best part about the entire show.
