On the contrary, I think most people love anime openings and endings, and I'm the exception for being very mixed on them. The visuals are usually well-detailed representations of the show, but J-Pop is a really inconsistent genre for me, I either love it or I despise it. I'm not much of an otaku in the first place anyway, most of the anime and manga I've consumed were as an outgrowth of some other interest (like sci-fi, or video games).

Been a while since I last watched anime, but I think my favorite opening might have been Cowboy Bebop's. The uptempo jazz, the silhouettes of all the characters and their signature weapons, the really cool transitions, it's all very close to perfect.
