Overall I would give the series a 7/10 vote ... i.e. it was "good". But imo it could have been better too. Classic example for my claim is the last arc - Haruka's. So much love was put into the storyline and the heroine that made it quite engaging. In retrospect it was sad that the other heroine's arcs did not get as much love and attention.
Still - even with that I enjoyed the season as a whole, though it was not "earthshaking" or something like that.
