How to tell a story in the least attractive way

Rating: 5/10 (4 December 2017)

The fact is very regrettable, the story must be told, racism must always be denounced and new generations must know what African-Americans have suffered in USA. However, it is not a good movie. The only reason I ended up seeing it is because it is based on real events and I wanted to know what happened in the end. If it were fiction, I would have got up from my chair in the first 30 minutes.
