I was not a huge fan of season one, it was agonizingly slow and spent way too little time on its actual sport. Now that there is a season two however, I would say that this anime became a decent experience.
Here in S2 we have a huge tournament arc with high stakes, some (finally) good character developpement and overall a nice watch experience. I would recommand Tsurune to fans, the whole 26 episodes show is now worth a watch if you are sports anime aficionado.
