Brazil is my favorite movie, and I will take your reference one step further to point out another scary thing that people tend miss on their first few viewings: there are no terrorists in the film, only routinely failing infrastructure, and the oblivious bureaucracy that places the blame on terrorism.
For completeness, I should say that Harry Tuttle does engineer one small disaster out of spite, but in general his M.O. is to go around fixing things without filing paperwork, and Sam Lowry sabotages the pneumatic tubes in his new office, but it's not suggested that everyone is as fed up as they are and therefor actively revolting against the system. The SWAT-style police entry and arrest of Buttle is also very destructive, as they fail to repair the damage, and then neglect it.
The real world does have actual terrorists, but they are similarly less threatening than our government and police and infrastructure.
