as an account of various people who lived under the Stasi. Also, The File:

The (again, factual) story of someone uncovering their own file and researching its history.
the inaccurate/ridiculous part is that he couldn't do what he did because every one of them had another agent(s) on them precisely to prevent such occurences. they spied on and controlled each other just like they did on citizens. other than that - great movie, and depiction of the strong influence such agencies had on personal lives (to make someone or destroy someone) is accurate.

Slavoj Žižek, reviewing the film for In These Times, criticized the film's perceived softpedaling of the oppressiveness of the German Democratic Republic, as well as structure of the playwright's character, which he thought was not very likely under a hard communist regime.[23] Anna Funder, the author of the book Stasiland, in a review for The Guardian called The Lives of Others a "superb film" despite not being true to reality. She claims that it was not possible for a Stasi operative to have hidden information from superiors because Stasi employees themselves were watched and almost always operated in teams
To anyone considering watching this, if not for the history, watch it for the movie's sake. You will not be disappointed at all.
