I wonder if there's any hard data on those points. I imagine someone must have done some research, although I really can't imagine that the popular perception of fantasy novel prologues has been the subject of much academic study...
I was thinking the same thing. I wonder why, if prologues are so hated, are they in almost every successful fantasy series I've read. I bumped this thread to find out how to write a successful prologue but all I see is great dislike of them.
