...I find it strange that this review criticizes the show's main emphasis on the teacher character rather than the students when the series is based on a book written by a real teacher detailing his experiences. It seems odd to expect the focus of the show to be otherwise.
I think the point is that he should have, and could have, been written
better. While transforming the school's theater department, the book's author also spends time coming to terms with his own sexuality; the TV version is a straight-washed, self-absorbed and often clueless man who stepped over a more qualified woman to get his new gig. There's little to like about Radnor's character.
My excitement to see this show had to do with our mutual friend who coincidentally also transitioned from English teacher at his former high school to head of its drama dept. His infinite talent made him a perfect fit, and I've found it impossible to go anywhere in his smallish college town without running into a former/current/future student demonstrating their respect and adulation for him; it's adorable!
Do let us know what you think about the show, MB.
