Art and Sound: Even for those who keep up with the manga and therefore know everything that will happen in the anime, it's like you're discovering what happens in the match again for the first time. If there were any blocks, receives, or plays you read in the manga that made you cheer in excitement, it was made even better in the show with the use of slow-motion sequences for dramatic effect, and the imagery of crows and eagles as symbolism for Karasuno's strength in numbers, willpower, and determination. As always, the songs used in Haikyuu are positive and inspiring, like it's saying you can accomplish anything you put your mind to without it sounding trite.
Character: Development is seen in secondary characters in big ways. Certain supporting characters get as much screen time as the main cast, showing backstories and idiosyncrasies to help develop the plot and give the show substance. This makes it hard for viewers to have just one favorite character.
Overall: It'll be a damn shame to not read and watch Haikyuu. It's a roaring good time and can entertain any viewer even when they have a preference for other genres.
