As it was the first anime I watched (other than pokemon), I may be a little biased Hunter x Hunter is the true definition of how to write a good story. The characters all progress through the story at a pace you can actually notice, it may as well have the best power system, the villains are perfect (in chimera ant arc specifically), the art is amazing and the story is engaging.

If I explained what I liked about every single character this answer would get to long so I’ll just talk about who I feel stood out the most to me, the main character himself, Gon.

From the start, he gets introduced as a character that wants to find his dad, though not as much is revealed at the start. Compared to other anime, all the main characters are introduced in the first few episodes so you don’t have to wait much. If we get into Gon’a personality itself you would see that he never really gets mad at all especially in the beginning and the plot favors him specifically for that, preventing his personality from changing at all. Though this pattern stayed for majority of the series, Chimera Ant Arc is where things take a change.

Gon basically learnt most of his Hunter knowledge from Kite. Though the anime didn’t show it, Gon valued him deeply. At the beginning of the Chimera Ant Arc, it’s revealed that Kite had been killed by Pitou. I don’t remember much so I’ll skip ahead to the point in the middle of the arc. Multiple times in the arc, Gon was shown to have a completely different personality than normal. He seems to have went insane and acts way differently.

His happy go lucky self had been emerged with something in the middle of madness, anger, sadness and regret while also showing that he was losing the terms that made him a protagonist and was starting to turn him into a hypocrite or something similar. This arc is way darker than the previous arcs and the writing for the characters is better than expected.

Even though many other characters in the series have amazing writing and majority of this review was me praising Gon’s writing and The Chimera Ant arc specifically, you still have to give it to the rest of the series arcs even though I found this one as the best.

I'll take some time to also review the plot and other characters.

The plot's original premise was something you wouldn't normally find anywhere else and the power system is amazing. The show manages to get multiple completely different arcs while staying on track of the original premise and all the characters are unique and show a kind of spectrum that differentiates every one of them. Some flaws are visible but I was able to look past them.

All in all this series is an amazing experience and I definitely recommend it as a fun manga that everyone should read at one point.
