Declined Film Review. Why?

I have written 176 IMDb reviews and do not recall ever being declined before my recent review of the film "Hannah Arendt", which was rejected and not published.  Although this film bore the name of the famous 20th century philosopher, the film was NOT a biography of Ms. Arendt but rather focused on a specific historical incident which inspired her iconic "banality of evil" philosophical concept. The movie was NOT about her entire life but rather about a specific incident, the trial of Nazi Adolph Eichmann, and how that single event influenced her view of totalitarianism.  It would have been impossible to review this very important film without seriously considering her viewpoint of the rise of Nazism during World War II in Europe.  I would like to know why IMDb declined my review.  This would help me in the future and would save time and effort as, unlike other reviewers, I spend quite a bit of time researching and writing my IMDb reviews and receive no compensation in return.
