I love sport, it’s a huge part of my life. So obviously, any anime that talks about sports interests me.
Volleyball is a really interesting sport, very fun to watch. Alas, 2.43 is not necessarily. It's not bad.. Just not very interesting. The pace is not inspiring and the relationship between the characters leaves something to be desired.
The matches aren't very intriguing, even if they're still quite fun. The “rivalries” are fairly well run, but everything goes way too fast, which is a shame.
I wouldn't go so far as to say it's bad, but it's forgettable. There was potential, like all sports anime, but it seems like they wanted to move too fast, I wonder why.
