I started reading this after someone recommended it to me and it's surprisingly entertaining.
I wasn't expecting such a high bodycount, at least.
Is the old series worth watching? I'm planning on starting the 2011-present series after I catch up with the manga.
Heaven's Arena: 2011
Greed Island: 2011
Hope this helps.
This so much
Honestly I'll probably just watch both.
Just watch the 2011 series
FUCKING THIS. It is so much better. The atmoshere is darker and it has better pacing.
Also HXH 1999 Opening 2 sets the episode better than any other shounen opening.
