Cowboy Bebop's soundtrack, opening, ending, and everything in between, is amazing. I make sure to never skip those. I'll also usually watch opening and endings that are interesting to watch and/or have good music; for a while, Bleach did this, showing different endings for different captains. It was pretty cool.
Besides that though, I usually do the same: skip 'em.
i watch all intro's & outro's at least once. if i like them, i'll continue to watch them. if not, i just skip it. (n_n)v
Yeah I do the same, if I dont like it then I wouldd just skip it or if I really wanted to know what will happen next on the anime I would Skip the Intro....
well... if the intro/ending is a good song then i'll listen to it, but if it's not then i skip it, or if i heard it too many times before then i skip it
