The term is too... blanket. It covers too many different things to be actually useful. This came out of a conversation with a friend last night where she called a character a Mary Sue, and I thought, no... well... yes, sort of. The character was created for the purposes of an agenda, but doesn't have all the faults of a Mary Sue.

Actually he's a Marty Stu (which I suspect you know).

Yeah, I was wondering if I needed to throw that in. But I thought the term was Gary Stu? ;)
