Bruce studied mathematics at Oxford University and used his education to teach children in the East End of London and Sylhet, Bangladesh. Before "42 Up", he married, and Apted broke the seven-year structure of the series to film Bruce's wedding, which was also attended by Neil. Eventually becoming worn down by teaching in the East End, Bruce found work at St Albans School, Hertfordshire, a prestigious public school. Between "42 Up" and "49 Up" he had two sons and was happily married to a fellow teacher. In "56 Up" he admits he still has a hard time expressing his innermost feelings, in particular to his wife, but is a happily devoted father and husband. Still teaching at a prestigious public school, he has no regrets at this point in his life about the development of his career path. A number of themes have appeared repeatedly over the course of the series. Questions about religion, family, class, happiness and psychological state dominate many of the interviews, as well as inquiries about the worries and concerns subjects have for their future. In addition, questions often take a personal tone, with Apted noting that viewers often respond to his questioning of Neil's sanity or his perception of Tony's success in life as being too personal, but that he has been able to do this because of the friendship he has developed with the subjects over the course of their lives. The series has received high praise over the years. Roger Ebert said that it is "an inspired, even noble, use of the film medium", that the films "penetrate to the central mystery of life", and that the series is among his top ten films of all time. Michael Apted won an Institutional Peabody Award in 2012 for his work on the Up series. In a list of the 100 Greatest British Television Programmes drawn up by the British Film Institute in 2000, voted for by industry professionals, "28 Up" placed 26th. The "Up" series has been criticised by both ethnographers and the subjects themselves for its editing style. Mitchell Duneier has pointed out that Apted has the ability to assert causal relationships between a character's past and present that might not actually exist. Apted has acknowledged this fact, pointing out that in "21 Up" he believed Tony would soon be in prison so he filmed him around dangerous areas for use in later films. Apted also portrayed the troubled marriage of Nick earlier in the film, although his time frame for anticipating their divorce was premature.
