Harry Potter fanfic cliches?

I have been reading HP/GW fan-fiction and the most I seem to find is when Harry is taken away by some powerful who want him to be powerful or suddenly has become powerful in magic and he bashes on Dumbledore or Hermione or Ron because they're not his allies or friends.Some are when he has a harem.Is this turning into Naruto kinda thing? Tell your honest opinions.
