I'm starting out by saying, hunter x hunter will always be my favourite shounen, BUT it's not for everyone. Even some shounun fans may not instantly like hunter x hunter. But those who do, love it, and I mean REALLY love it.
I went in expecting a couple of kids exploring the world, with some action and wacky characters and creatures. What I got out of it was so much more. The action elements, fight scenes are some of my favourite anime fight scenes, and the characters are all mostly unique and really grow on you.
It's a fairly long anime, but I loved every arc that it gave me. Hunter x Hunter may not be the jam for some people... But I loved it till the very end!
