haikyuu!! is probably one of my favorite anime of all time!!! i'll start this off by saying i don't usually enjoy sports anime. i usually think they're bland and predictable. haikyuu!!, however, is neither of those things!!
one of haikyuu!!'s best points in my opinion is it's characters. the characters in haikyuu!! are very lovable, and they're all very unique! for me, it's impossible to choose a favorite character from haikyuu!!
the story in haikyuu!! is also very nice! what i like about it that differs from other sports anime is that it seems like whole teams want to improve together, instead of individual members. the story is about karasuno climbing the ranks and becoming an amazingly powerful team, and it's about every team member's involvement. i also like that the story includes a lot of background on other teams!
the animation in the anime has some incredible spots, as well. it makes everything seem so impacting, which is fitting for haikyuu!!
overall, i think haikyuu!! is amazing. even if you dont like sports anime, you will probably enjoy haikyuu!! it offers something for everyone!
