It’s definitely my favorite!
It starts of as simple lighthearted show, but gradually the storyline intensifies and becomes much more complex and deep.
The plot is amazing and often unpredictable.
Great and diverse well-elaborated figures, which are rarely just simply good or bad along with outstanding character development.
The Nen power system might be a little confusing, but is really exciting and interesting to dig in and explore. Very well-balanced and full of logical thrilling surprises.
Powers with numerous possibilities that have their pros and cons, power-ups and limitations.
Vast intriguing world, great musical background and amazing action scenes.
The only disadvantage for me personally are the hiatuses of the author, after the end of the 2011 anime.
Recommend to an anime pro as well as a newbie, the viewer kind of grows along with the development of the story :)
