This is a remake of the first Hunter x Hunter anime that was released in 1999.
For a remake this anime is rather good compared to most others.
This one tries to stick to the manga as much as possible but for some reason has been made very "casual" or should I say that its censured compared to the manga and the 1999 version.
And for the character development I find it weaker then the first one but you still get a hum of what everyone is striving for.
I'll make this short though.
I'd rather watch the 1999 version over this because it has more story ,sticks to manga + fillers with some character backstory and ofc no cencuring.
But if you like better animation, effects and sound this is a better choice.
