Yes. It was the changes that made Faramir so much less noble that annoyed me the most, especially as he is my favourite character. I wouldn't mind so much being left out if there weren't so many silly pointless things added and he had made the battles shorter - I found the battle scene really dragged and seemed to add little to the plot.

Certainly trying to find the good is the way to go. I think no matter the percentage, part of the point is that I feel that fanfic isn't that removed from any other form of fiction in how much is bad - and at least I don't have to pay for it to find out what I like. It is one of the reasons I very rarely go to the cinema - paying that much money to see a film unless I know I am going to like it feels wasteful. :)
