No, no... There is never enough length in chapters when you run across a good fic. However, what there IS too much of is endless details. It's like Tolken honestly, while I love Lord of the Rings, I DON'T want to spend two and half pages reading about how a specific part of some stupid forest areas looks like.
Hey if there's a chapter to be posted then I'm not gonna complain about how long it is, the longer the better to me, the only fic I can remember thinking that the chapters were just too damn long was this one Eva one I read, I forget the title but I've got the link if you want it, it had some crazy amount like 100,000 words per chapter, and there were a lot of chapters, but of cours ethe longest fic I've ever seen period has probably got to be that infamous Ah My Goddess fic 'Trial By Tenderness' which was the second fic I had ever read.
