"Once More With Feeling" is a good episode but it's unusual because it shows, for a while, Professor Kingsfield in a rather poor light. While he often seemed mean and demanding in the show, he was, in his own way, very fair--but this fairness was not evident during much of the show. Fortunately, in the end, he came through when needed. Maybe this is a good thing, as too often in the show he comes off as robotic--here he is clearly quite human.
The show begins with Logan meeting with Professor Howard (Robert Reed). Very soon she realizes that he is making a pass at her and suggesting, in a clever way, that her grades will improve if she attends 'private tutoring' with him. She is appalled and naturally angry. While she has no direct proof, she did the responsible thing and approach the head of the school's Ethics Committee--Dr. Kingsfield. Oddly, Kingsfield is rather rude and dismissive when she tells him what happened. Soon after, however, Kingsfield does begin to investigate, but it is surprising how nasty he was to what he would see as the potential victim.
Despite this odd reaction, however, the show was well made and brought very important topics to the fore--something that made it a very important show for the time. It also addressed affirmative action, disabilities and many other themes rarely seen on TV at the time--and in intelligent and engaging plots. Like the rest of the shows in the series, well worth seeing.
