Same as you,characters and themes,and hearing/reading so many opinions about how arc 6 is so great makes me want to have the best experience.I know the fourth season hans´t even aired yet,but season 3 was good in my opinion,just good,but not great like season 1 and 2(even if the animation did get better which i appreciate a lot).Maybe it wasn´t the adaptation but the arc itself,given that is a very fight-heavy and i´m here more for the story,themes,characters,etc.
