The movie is excellent, but I wish they had skipped some of the over dramatization. The bathroom issue was completely made up for the movie as that facility did not have segregated bathrooms when she worked there. Don't think of this as an excellent movie about a black woman; think of it as an excellent movie.
And speaking of excellent movies, my wife and I saw Harriet when it came out a few months ago. Again, they created stuff for the movie that they didn't need to in my opinion, but it is another excellent movie worth seeing. In my opinion she needs to be put on the $20 bill as soon as possible.
