Haikyuu is just great anime. I watched all season with tension and enjoyment. Characters were very well-balanced and It doesn't feel that Hinata is the main character. For pros, It wasn't that many backstories to fill the time, also there weren't the weird and edgy moments that many anime had. The last episode was really good and the best so far. The art style was also in that season the best from all season, you can see that they put a lot of effort into it. If you have no that much freetime you can watch a movie but I recommend that season instead.
