For some reason on TV shows, I'll insist on watching the opening theme every single time. I guess it helps set the pace of the episode. Otherwise it feels a bit lopsided after a cold open. But I'm probably being OCD about it, since I'm meant to watch a show with commercials and such. Plus it's fun to be able to sing along in Japanese to anime opening credits (watch me with Neon Genesis
"zankoku no tenshi no you ni...") Some
shows may let you hit the Next Chapter button to skip the opening credits, but only if the disc is structured that way. So a DVD that count a full episode as one scene won't work.
+1. this is very interesting.
