"This is an odd topic, but funnily enough, cinema hasn't been much of a stranger to it. The 'teacher-student' romantic relationship is a good base for a plot because with it comes an obvious sense of tension, secrecy, & awkwardness. The emotions are all there and gives the film that utilizes this topic a chance to develop characters as the relationship further grows. Though we'd always go for cinematic excellence over financial returns, for filmmakers going about this sort of romance in their pictures, the outcome might not always be in their favor. For this reason alone, the 'teacher-student' relationship is a risky subject to tackle and, therefore, not always easy to get right. The films in the list below have covered this plot-line in interesting and/or innovative methods, which have helped them secure a connection with the audience, all the while taking a chance that has every possibility to misfires." - thecinemaholic.com
