Key parts of the review:
"I saw Graduation as a drama promoting the basic values of teamwork and honesty - virtues that were especially important as a way of resisting the perpetual attempts made to prevent Henglaar from continuing his work. Henglaar himself is something of a maverick figure, an aural equivalent of television's favourite Dr. House (but without the limp).
The production values are refreshingly high, with a large cast performing a variety of roles, accompanied by atmospheric music (from Mary Kouyoumdijan). This drama appeals to aficionados and non-aficionados of Star Trek alike."
