This series is the latest in the Bouei-bu franchise, which I recommend, especially if you are a fujoshi, fudanshi or an enjoyer of the unclothed male physique. I don't think Haikara is as good as the other seasons, but I still recommend it. An all-male cast of cute guys who are often naked is always a pleasure to watch. It's funny and has loads of ships and fanservice like the other seasons but it did not feel like as much as there was in seasons 1 and 2, for example. The character design and animation are very different from the other seasons and IMHO (In MyHaikara Opinion) inconsistent and clumsy in places. But otherwise, the familiar plot structure and setting are just as fantastic and enjoyable as the others.

I have a feeling there will be more seasons because it's still not been explained where the defense club sign came from...
