Director doesn't divert anywhere and show us what was really happened. There are no surprise elements except the one in the revealed at the end. So keep your expectations low. If you are a person who knows already or if you have read all these somewhere regarding what happened in 1996 better stay away there is nothing left for you in theatres.
The problem with the movie you will be expecting something big to happen but nothing happens at all but at the end of the movie a news reel with snippets tells us why this kind of movies should be made.
There is not much change for them in these 25 years, be it left or right.
