Team 8 was one of the first For Want of a Nail fanfictions I ever read for Naruto and it honestly gave me a taste for them. There are several times when I've told friends and family that I prefer this story to canon. It's well thought out, the plot is interesting, the prose is fantastic, and when you read it you feel like something is finally going right for the characters.
Sometimes you don't want to read about the world ending, and even though there are some definite world-ending scenarios in this fic there always seems to be a bright moment of awesome or funny or adorable to sooth your pains away. It is most definitely worth the hours it takes to read.
Most of the complaints of the others be explained by the story's age—it began and was first plotted in 2006 before a lot of plot devices in canon came to light. And if you're really that bothered by a more thoughtful Naruto, why are you reading FWOAN fanfictions to begin with?
