sharp writing, well that's kind of a given; casting first class with Denhom Elliott, Joss Ackland - who steals the show with his larger than life hair and presence - Glenda Jackson, and David Threfall to name just a few of the understated right on the money performances. the school is a seething mess of nasty undercurrents, jealousy and contempt and Smiley with his usual nondescript doggedness, digs up the canker and exposes the rot. This was written before Tinker Tailor and sets the stage for the Smiley that is to come. BTW it features and young and talented, Christian Bale :)
