I'm the same. One of the first fantasy series I read was the Belgariad, and after that I read just about everything Eddings, even though they were extremely similar in characters, storyline and other bits and pieces. But I stilll enjoy reading them in spite of that. It's perfect for when you want to read something which you won't be surprised or shocked by, something that isn't too dark or brutal, or something that doesn't take too much brainpower to figure out. Well, that's the way I look at it, anyway.
I know that there are better books out there, but I don't mind that. I keep reading them because they bring back good memories, and because I enjoy the stories, even if they are rehashes of each other.
