This anime was SOOOOOO close to becoming a masterpiece. Heres why:
The story was so well written, with decent world building and exceptional character development.
The art was a massive improvement to the original version, and the animation was amazing.
The music is so iconic, and i loved the fact that they kept the same opening for the whole of the anime.
ALL of the characters are interesting and very strong/intelligent, especially Killua, despite being a side character - and the MCs best friend - he stole the spotlight for me, and i'm pretty sure that everyone else can agree that hes one of the best/IS the best side character in the anime.
I enjoyed this anime so much up until the Chimera Ant Arc, the narration took over and kept dragging on the same scene for 20 episodes, the pacing was horribly slow, which i know was because they had caught up to the manga, but still, it was boring.
Then after the Chimera Ant Arc, The MC met a certain person, however it was so anti-climactic, that it disappointed me. All that tension and build up for this scene, was ruined.
