Wow. I usually shit on this manga but I never got a Naruto/Sasuke vibe at all. I would say it was decently unique. Because it was sort of a long time coming. Natsu getting mad after seeing Lucy's eye plopped out, and Grey coming to the realization that most people he loved died due to the demons.
Yes, it does feel stupid like Naruto, but I wouldn't really compare the two at all. Both were stupid at their own way.
