As to Kvothe, guys, I keep assuming that what spares him is that 1)Rothfuss knows Kvothe is one 2)The whole point is that Kvothe was a legend and now he's washed up and 3)Kvothe himself probably lies during large parts of the story.
But I mean, he's supposed to be one is all.
I went to a Rothfuss book reading, and he mentioned that he got the idea for the series when he was Casanova's autobiography, where he is basically writing this book that plays up what a great adventurer he was and how many women he slept with.
So it's possible that stuff like Kvothe being the world's greatest sex machine is really the invention of an unreliable narrator. It doesn't make it any less insufferable to read, though. The book is not set up for you to root against young Kvothe, because there is really no one else in the series to root for. At least in The Wheel of Time - another fantasy series with serious Mary Sue issues - you get a few non-obnoxious characters to balance things out.
