No spoilers. What I would say is "not bad"
While it has its own definition of "fun", this anime isn't a very bright one to its genre. Like when you say "Harem", you have a sea of titles waiting for you to watch. This doesn't shine much in comparison to them.
While this anime is not the brightest, The animation quality is very good and the character designs are especially good. Not very good soundtracks either...
While the story is focused on the normal life of high school students without any form of twist so it doesn't pack the punch which you need at the end of a season.
Its better to say you can try to see this anime for taking a break from watching other anime and it is basically impossible to binge this show
