The Promise, the grandest big-screen portrayal ever made about the mass killings of Armenians during World War I, has been rated by more than 111,300 people on IMDb — a remarkable total considering it doesn't open in theatres until Friday and has thus far been screened only a handful of times publicly.

The passionate reaction is because The Promise, a $100-million movie starring Oscar Isaac and Christian Bale, has provoked those who deny that 1.5 million Armenians were massacred between 1915 and 1923 by the Ottoman Empire or that the deaths of Armenians were the result of a policy of genocide.
