My Brilliant Friend

Can anyone tell me what do they find good in Ferrante's work? I have been through the first of the Neapolitan Novels and I don't see it. I remember a pretty bland story (didn't help that I had been reading Erri de Luca, which also write about post-War Neapolitan youth with much more poetry), with some dull gimmicks (intensity shown by saying the same thing thrice). Apparently, it is on 35 shelves in here. How wrong are you people? How wrong am i?
