Not really, no. In my let's plays I tend to let the credits roll for 'archival purposes', as I like to look back at older games and cover them as extensively as I can through that medium. But for personal play, only if there's an achievement and I'm generally not watching them as such.
I do however like when games allow you to mess around with the credits, like tap letters and names and cause them to disintegrate, crumble or explode, or you can shoot them like Space Invaders. It's rare you'll find a game that has such things these days, but it's appreciated when I get the chance.
