I read this past week's issue of All-Star Western, the one with Superman on the cover. Superman only appeared for the first seven pages before leaving, allowing the story to move on to what it was actually about.
I really don't like this sort of guest appearance. As the thread title says, I find them pointless. Don't get me wrong, guest appearances by big characters aren't something I dislike in and of themselves. Having said that, I do prefer to see them when there's an actual point to them other than just giving a comic book company the opportunity to place a character on a cover in order to bump sales.
Thank you Troy for the sig
