Another serious problem that I see in this work is -in my opinion- the excessive polarization of the heroines, because Kasuza and Setsuna are presented in a diametrically different way within the story, which seems to me an arbitrary decision on the part of the scriptwriters, comparable - without exaggeration - to this; As said before, while one is presented as a more serious and mature character, with more time on stage, development, and emphasis on her problems, the other presents an incredible level of caricature, little goes into her conflicts, and has fewer difficulties ( or at least that idea leaves the series) and ends up looking more like an "intruder" than an equal opportunity heroine within a love triangle. Here the predilection for one of the protagonists is too noticeable, and that greatly damages the development of events.
In short, this anime is one of those works that -from a general point of view- are acceptable, but could have been better if bad decisions had not been made during its development. If the story had remained in the same tone that it had been doing from the beginning and had not degenerated into an elaborate drama, chapters as bad as the one on the hot springs (image above) or the one in which Kasuza cold, replacing them with really important content (such as more emphasis on Setsuna's background, thus giving her the protagonist treatment she really deserves) and/or keeping the focus on the musical part, would have turned out much better.
