I have to say that Eroninja is good for not falling into several tropes I hate with Naruto fiction, like a lot of anime adaptations having Sakura be high up in the pecking order, while Hinata is ignored, and Haku telling the truth with 'That One Line'.
Also, it has a deep plot, and goes beyond Naruto making a harem out of every girl in the Elemental Nations, and even into plots within plots within plans like the series it's from.
I look forward to the chapter named 'Target: Kaguya'.
