Sometimes, you can love a game while secretly hoping that the main dude(tte), often your avatar, dies in some horrible fashion, never to return, while anyone else steps in to take over. It's the annoying hero syndrome, and while it isn't that frequent in gaming, it often strikes at the worst moments (like in otherwise awesome games). Worse, sometimes it can happen in the middle of an otherwise decent franchise. Sometimes it's just a sub-character (whew), but not always.
But enough with the details. What playable characters that you've been stuck with have you hated?
