Of what movie genre is 2007's "The Page Turner" a good example?

The 2007 release The Page Turner is a psychological thriller.

Directed by Denis Dercourt, the French film follows Mélanie Prouvost, a gifted young pianist whose childhood humiliation leads to a carefully planned act of revenge. She becomes the page turner for celebrated concert pianist Ariane Fouchécourt and gradually inserts herself into Ariane’s professional and personal life.

The film builds suspense through restraint rather than conventional action. Mélanie’s outward calm, deliberate behavior, and unclear motives create an atmosphere of psychological menace. The story is driven by obsession, manipulation, memory, and emotional revenge—hallmarks of the psychological-thriller genre.

The movie was originally released in France in 2006 and screened at the Cannes Film Festival that year; its international and U.S. circulation is associated with 2007. That release-timing difference explains why it is often described as a 2007 film. It is also sometimes labeled drama or mystery-thriller, but psychological thriller is the most specific answer.
