I first started watching this series from a recommendation from my friend, and it turned out to be quite a jewel. In fact it got a wopping 4.5 out of 5, here are the details not already mentioned in the synopsis:
The animation in
Hunter X Hunter is well drawn and most of the art work is very smooth. The sound is above average at most, but the intro/outro make up for it because they are really quite catchy, and well written (although they may seem short.) The character design and personalities are top notch, with each and every character having their own special attributes that makes them shine.

The story is what really pieces this great anime together very nicely. It may confuse people though, because even though it is about Gon looking for his father, it mainly focuses on him meeting new people, and having his own little adventures. Their is also a fair amount of humor added here and their to really make this anime very enjoyable.
Overall I would recommend
Hunter X Hunter to anyone who likes any type of action/adventure/comedy or just good fun in an anime. Those of you (and I know their are many), who watch the anime Naruto will LOVE this one, I guarentee you that.
So What Are You Waiting For??? GO GET IT NOW!!!
