No: while the choice to make this film look like a video from the period (and very ugly in the process) is a bit mind-boggling, there is little else in here that is a mistake. It’s an interesting story that enables the director to display a particular place and time, including the tension and the uglyness that exists in a military dictatorship. Maybe the choice of making the footage ugly was not so misplaced after all. (As a side note: while the process as shown here is certainly simplified, this does not reduce the value of this work. There is a whole genre, documentary, that is supposed to adhere to the truth more closely. This is a political drama.)
